Solid Carbide APX End Mills

Haas Apex Performance

 

Engineered for demanding machining applications, our Haas APX end mills are made from premium-grade micro-grain carbide. This ensures maximum hardness and wear resistance, resulting in the longest possible tool life, even under aggressive cutting conditions. Ideal for high-speed operations, tight tolerances, and production environments where consistency and tool longevity are critical.


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.

High-Efficiency Perfomance Milling (HEPM)
HEPM series milling cutters are center-cutting, 6-flute carbide end mills designed for high-speed trochoidal/peel milling of steel, stainless steel, cast iron, and some high-temp. alloys. Similar to the HSPM1 series of cutters, these tools excel in heavy cutting of materials with hardness levels up to HRC40, due to their superior chip pocket design and excellent chip evacuation capabilities.

• Unique chip splitter design reduces chip length by up to two-thirds, and a high 45° helix angle allows for excellent chip evacuation qualities and lower cutting forces, especially in heavy roughing applications
• Unequally indexed, or variable pitch cutting edges improve overall cut stability, and further reduce or eliminate unwanted harmonic vibrations, commonly known as chatter

High-Efficiency Hard Milling (HEHM)

HEHM series milling cutters are 6- and 8- flute carbide end mills designed for high-speed trochoidal/peel milling of steel and some hardened metals. These tools are designed with relatively higher rigidity than HEPM milling cutters, making them primarily suited for finishing operations, with exceptional performance in materials with hardness levels up to HRC50.

• 45° helix angle for higher productivity, reduced cutting forces, and longer tool life
• Lack of unequal flute indexing is advantageous when paired with lower machining speeds, for improved surface finishes

High-Speed Performance Milling 2 (HSPM2)

HSPM2 series milling cutters are center-cutting, 4-flute carbide end mills designed for high-speed machining of steel, stainless steel, cast iron, and some high-temp. alloys. These general-purpose end mills have a special edge geometry that significantly reduces vibration and noise during a cut, and are offered in different chamfer and corner radii for improved strength in roughing applications. 

• Unequal, variable pitch flute spacing and multiple helix angles (on some models) between 35° and 38° provide superior chatter reduction, enhanced edge strength, and improved cut stability during heavier roughing operations, while 
• Enhanced corner geometry for longer tool life, maximum chip removal, and improved productivity

High-Temperature Milling 2 (HTM2)

HTM2 series milling cutters are center-cutting, 5-flute carbide end mills designed for high-speed machining of stainless steel and high-temp. alloys, and some steels and cast irons. HTM2 end mills improve on the dual-core design of HTM1 end mills by enhancing chip space in heavier cuts, while still maintaining overall tool rigidity.

• 38° single helix angle minimizes tool lift, provides resistance to deflection, and produces larger chips for removing greater amounts of material
• Modified dual-core geometry improves on HTM1 milling cutters to provide outstanding performance in roughing applications, especially in deep slotting and heavy profiling

 

Aluminum Titanium Nitride (AlTiN) coating has a higher aluminum content than TiAlN, making it harder, with better lubricity. The drawback is that edges can chip in very hard materials.
