Allied Machine
& Engineering

Allied Machine & Engineering is the ideal partner for manufacturers dealing with challenges such as tool breakage that causes line stoppages or dimensional instability when machining difficult materials.

The company offers a variety of high-durability coatings, such as AM420, selected based on the application.
When combined with cutting-edge geometries optimized for specific machining conditions, these solutions help reduce tool changes and minimize machine downtime.

For mass production with mild steels, the HPM drill provides excellent stability. For deep-hole or interrupted cutting, the HPM2M ensures precision and reliability. When dealing with difficult materials, the HPS excels at improving yield.
Each drill type is designed to enhance tool life and machining consistency.

Note: Performance may vary depending on product type and machining conditions such as spindle speed, feed rate, coolant, and machine rigidity.

How to Choose Allied Machine Carbide Drills

General Steel Drilling

Recommended: HPM

If you machine carbon steel, alloy steel, structural steel, or tool steel in production, the HPM drill is designed for stable, efficient holemaking.

Its straight cutting edge and optimized clearance angles help reduce cutting resistance, rubbing, wear, and chipping. The geometry also supports smooth chip formation and helps reduce burrs at the hole exit.

AM420 coating improves heat resistance and tool life. TiCN coating is also available for specific materials such as aluminum bronze.

Best Suited For

• General steel drilling
• Mass production
• Carbon steels
• Alloy steels
• Structural steels
• Tool steels
• Applications where burr reduction is important

Available Lineup

• Diameter range: 3.00–20.00 mm (approx. 0.118–0.787")
• Recommended depth: up to 8×D

Deep and Interrupted Holes

Recommended: HPM2M

If your application involves deep holes over 8×D or interrupted cuts, the HPM2M drill is designed for added guidance and stability.

Its double-margin design uses two guiding lands per flute to help maintain straightness from the start of drilling. This is useful when machining cross-holes or parts with inconsistent tool engagement.

The added stability also supports smoother chip evacuation, tighter hole tolerances, and better surface finishes.

Best Suited For

• Deep-hole drilling over 8×D
• Interrupted cuts
• Cross-hole applications
• Carbon steels
• Alloy steels
• Structural steels
• Tool steels
• Applications requiring straightness and tight tolerances

Available Lineup

• Diameter range: 3.00–20.00 mm (approx. 0.118–0.787")
• Drilling depth: over 8×D

Difficult Materials

Recommended: HPS

If you drill stainless steel, titanium alloys, HRSA materials, or high-strength steels, the HPS drill is designed for stability in hard-to-machine materials.

Its radius edge helps distribute cutting forces at the tool tip, while the cam ground geometry reduces chipping and vibration. This helps control tool deflection and supports straighter holes from entry to exit.

AM420 coating is available for steels, while AM460 coating offers higher heat resistance for stainless steels and heat-resistant superalloys.

Best Suited For

• Difficult-to-machine materials
• High-hardness and high-strength steels
• Austenitic and martensitic stainless steels
• Heat-resistant alloys
• Titanium alloys
• Gray and ductile cast iron
• Applications where vibration and deflection must be controlled

Available Lineup

• Diameter range: 3.00–20.00 mm (approx. 0.118–0.787")
• Drilling depth: up to 8×D
