Solid Carbide End Mills
Value Performance
Our Value end mills feature high-quality micro-grain carbide that offers an excellent balance of durability and cost-efficiency. Designed for general-purpose use, these tools deliver reliable performance and extended tool life across a wide range of materials and applications. Perfect for job shops, prototyping, and everyday machining where value and dependability matter most.
HEPM and HEHM series milling cutters are designed for side-cutting and trochoidal/peel milling toolpath strategies. High-efficiency and high-speed milling toolpaths subject the end mill to a light radial depth of cut (Ae) and heavy axial depth of cut (Ap) at high feed rates, with reduced tool stepover for more radial passes. This dramatically increases the material removal rate, while decreasing cutting pressure, reducing and dispersing heat, reducing tool wear, and improving surface finish. Combined with chip thinning, high-efficiency milling, and high-speed machining toolpaths, these tools provide superior chip evacuation to carry heat away from the tool and workpiece. Center-cutting capability means these end mills are capable of conservative ramp and helical entry tool paths.

Chip Splitters and Roughing End Mills
When you're machining pockets with an end mill it's not uncommon to get a stack of chips in the pocket that's hard to get out.
Mark takes a look at several styles of end mills that cut your chips into smaller pieces, making them a lot easier to get out of the pocket before your end mill gets damaged re-cutting those same chips.
Square
• Corners have a sharp, square profile
• 90° cutting angle
• Most common corner type
• Used for slotting, profiling, and plunge milling
• Creates flat bottoms with square corners
Chamfer
• Corners have 45° chamfer
• Helps distribute cutting forces evenly
• Prevents damage to the end mill
• Extends corner life
• Creates flat bottoms with slightly chamfered corners
Radius
• Corners have slight a radius
• Helps distribute cutting forces evenly
• Prevents damage to the end mill
• Extends corner
• Creates flat bottoms with slightly radiused corners
2-Flutes
Recommended for non-ferrous materials. Two-flute end mills have long been the industry standard when cutting aluminum and other non-ferrous alloys, where chip clearance is important to efficient material removal. The massive valleys between the two flutes accommodate the larger chips produced by high feed-per-tooth feedrates on softer materials.
3-Flutes
Recommended for non-ferrous materials. Fewer flutes allow for excellent chip clearance on larger chips, and deeper cut depths. Ideal for aluminum in heavy roughing and finishing applications.
4-Flutes
Recommended for ferrous materials. The low flute count allows for excellent chip clearance for general purpose roughing and slotting. Ideal for steel, stainless, and cast iron.
5-Flutes
Recommended for ferrous materials. Higher flute count increases the tool strength, but reduces the cut depths. Ideal for finishing or high-efficiency milling in steel, stainless, cast iron, and harder materials.
6-Flutes
Recommended for ferrous materials. High flute count yields a thicker core for greater tool strength and less deflection, while increasing material removal rates. Ideal for high-efficiency/high-speed milling in steel, stainless, cast iron, and high-temp alloys
