Endmill is a cutting tool used for end milling operations. Endmills or Milling cutters are utilized in CNC machines. CNC stands for Computerized Numerical Controlled.
Endmill tools are accessible in a wide variety of lengths, flutes, diameters, and types and are chosen for concurring to the material they are cutting and surface finish required for the product.
Endmill is a cutting tool used in various machines like milling and turning machines. They are utilized for Reaming, Slotting, Drilling, Contouring, and profiling as well. Their physical appearance is commonly confounded with a Drillbit but they are diverse in numerous ways. Drill bits cuts axially (in one direction) and the Endmills cutter can cut in axially and laterally (multiple directions). This comes in helpful with accuracy cutting
Endmill Tools is utilized in Machines Parts, sign making, plastic cutting, mold making, wood inscriptions, mold making, and circuit boards.

Solid Carbide Endmill 4 Flute:
endmill available in 25 TO 40-degree helix, used for general milling is most of the medium hardness materials like steel, SS, brass, iron and nonferrous material made from premium sub-micron grade.
Solid Carbide Rougher Endmill
ACCUSHARP Cutting Tools manufactures an assortment of rougher’s for a wide extend of materials and conditions. Heavy cuts can be achieved because our roughing endmills have a much higher compelling bolster per tooth than a conventional end mill. Normally a 20% reduction in
effective horsepower is used. Roughers have chip-breaker cutting edges, the “peaks” on each cutting edge give the cutting action producing short fat chips rather than long stringy chips produced by conventional mills.
Solid Carbide Ball Nose Endmill (2 Flute)
The design of a two-flute ball endmill permits plenty of chip evacuation making them most effective in contouring deep pockets in mold and dies. Utilize for radius and contouring part, surfaces. Designed to cut materials extending, from nickel base alloy, stainless, tough alloys, abrasive and nonferrous.
Solid Carbide Ball Nose Endmill (4Flute)
The Design of a four flute ball end mill has less chip evacuation due to their design with multiple cutting edges they can produce a very smooth finish by running lighter chip loads, without sacrificing a high rate of production.
Accusharp manufactures & exports Carbide Ball Nose Endmills in 4-Flute Ball Nose for varied types of material machining ranging from Aluminum, MS, Alloy Steel, Cast Iron, Stainless Steel (SUS), Hardened Steel machining up to 70HRc, Inconel, Titanium, and other Exotic Materials. Fine geometry with 4 flutes designed to adapt to different profiling conditions.
Tapered Endmill
Tapered Endmill is meant with a leading edge that tapers at the end. They are used in several dies and mold applications.
Keyway Endmill
Keyway endmills Cutter are utilized to make form spaces in parts so that key stock can be embedded into the spaces when mating other components with the parts. Keyway end mills are regularly undersized, which suggests they make an undersized opening. This guarantees a cozy, secure fit when the key stock is embedded into the slot.
Corner Radius Endmill
Corner Radius Endmill Cutter has a rounded cutting edge and is used where a specific radius size is required. Corner chamfer endmills have a calculated cutting edge and are utilized where a particular radius size is not required. Both types provide longer apparatus life than square endmills.
Corner rounding Endmill
Corner rounding Endmill Cutter utilized for milling rounded edges. They have ground-cutting tips that strengthen the end of the tool and decrease edge chipping.
Profile Endmill
Profile endmills Cutter refers to the shape of the cutting end of the tool. It is utilized in profile milling operations.
Serration Endmill
Serration Endmill as a Special Endmills or Crest-cut milling tool utilized in roughing operations to decrease the cutting forces and increase the efficiency.
Hole Mill Cutter
A Hole mill cutter is generally an undersized reamer with a boring geometry i.e. the estimate of the hole mill is usually 0.2-0.6mm quite the estimate of drill in order that there are not any drill marks on the opening plus the opening axis is corrected for ensuing reaming operation.
Thread Mill Cutter
Thread mills are utilized to produce threads on machining centers that are capable of helical interpolation. The benefits of thread milling versus tapping are particular to the needs of the customer. Thread mill helical flute design reduces chatter. It is well suited for stainless steels, titanium, and alloys, high-temperature alloys, non-ferrous materials.
Flute Types
Flutes highlight grooves or valleys that are cut into the tool body. A better number of flutes increases the quality of the tool and decreases space or chip flow. Endmills with fewer flutes on the cutting edge will have more chip space, while endmills cutter with more flutes are going to be ready to be utilized on harder cutting materials.
Single Flute End mill designs are utilized for high-speed machining and high-volume material removal.
Two Flute End mill designs have the foremost amount of flute space. They permit for more chip carrying capacity and are utilized basically in slotting and pocketing nonferrous materials.
Three Flute End mill designs have the same flute space as two flutes, but also have a bigger cross-section for noteworthy quality. They are utilized for pocketing and slotting ferrous and nonferrous materials
Four/Multiple Flute Endmill designs permit quicker feed rates, but due to the reduced flute space, chip\moval may be an issue. They create a much better wrap-up than two and three flute tools. Perfect for peripheral and finish milling
End Cut Types:
End Mill Coating
Titanium Carbonitride COATING ON END MILL (TiCN) is harder and more wear-resistant than Titanium Nitride (TiN. It is commonly utilized on stainless steel, cast iron, and aluminum alloys. TiCN can give the capacity to run applications at higher shaft speeds. Utilize caution on nonferrous materials since of an inclination to rankle. Requires an increment of 75-100% in machining speed vs. uncoated tools.
Sizes: Estimates extending from Ø 2mm to Ø 32mm
The raw material used:
These Endmills are made from Tungsten Carbide provided by worldwide brands. We have advanced facilities, machines, and process equipment for manufacturing these products.
Up Milling and Down Milling Operation.
Difference between Milling and Down Milling Operation.
| Up Milling | Down Milling |
| In up milling operation, Chip load on teeth (or uncut chip thickness) increments continuously from zero at the point of engagement to most extreme at the point of separation. | In Down milling operation, Chip load on teeth (or uncut chip thickness) decreases continuously from a maximum at the point of engagement to zero at withdrawal. |
| In this operation, the Table turns against the direction of the table feed. | In this operation, the Table turns along the direction of the table feed. |
| At the starting of engagement, teeth rub will lay or nourish marks on the machined surface. This makes strides surface wrap up. | No such rubbing activity takes put and hence lay marks remain intact on the machined surface. |
| Here, the tooth encounter continuous loading as contact begins with zero chip load | Here, tooth involvement affects loading as the tooth locks in abruptly with the most extreme chip load. |
| In up milling, horizontal axis milling machine, cutting drive in up processing mode is coordinated upward. Hence, it tends to lift the workpiece from the workable. Appropriately, unbending and costly installation is required for immovably mounting the workpiece. | In down milling, operation mode, the cutting constrain is coordinated descending, and in this way, it tends to press the workpiece instead of lift-off. So cheaper installation can be utilized. |
| Thin workpiece tests, in case, machined utilizing up milling mode, may get misshaped due to upward cutting constrain. | Chances of mutilation of thin workpiece tests are less with down milling mode on the off chance that legitimate support in the bottom is given |
| Due to progressive build-up of chip load in an up milling operation, heat emission is high. So, there exists an inclination of chip welding with the teeth. | The inclination of chip welding is less in down milling but chip re-deposition on wrapped up surface happens as often as possible that debase the quality of the wrapped up surface. |
| In this operation, Burr is shaped as it were on an unfinished surface ahead of the tool nourish, the larger part of such burr is evacuated within the consequent passes. | In this operation, Burr is shaped on the finished surface on the inverse side of the tool feed. In this operation, the burr is not evacuated consequently. This leads to debased cutting quality. |
| Other than making surface wrap up, rubbing amid engagement may result in undesirable work solidifying owing to critical heat emission. | Chances of work solidifying are negligible with a down milling operation. |
| In up milling operation, No backslash eliminator is required. | In Down milling operation, a Backslash eliminator is required, particularly in case the milling machine is older one. |
