Precision HM Coolant Through Straight Flute Drill Solid Carbide Drill For Hole Machining

The Solid HM Internal Coolant Straight Flute Drill is a high-performance carbide drill bit precisely engineered by AMG. Manufactured from ultra-fine grain solid hard metal (HM), it offers outstanding strength, superior wear resistance, and excellent heat stability. Designed with a straight flute structure and integrated internal coolant channels, this drill ensures efficient chip evacuation and rapid heat dissipation during drilling. It is widely used for high-precision hole machining in stainless steel, aluminum alloys, titanium alloys, and other non-ferrous metals.

It is the ideal tool for deep-hole processing in industries such as aerospace, medical devices, mold manufacturing, and automotive engineering.

Applications

• Drilling stainless steel and titanium alloy components in medical devices

• Composite material drilling in the aerospace sector

• Deep and micro-hole processing in precision molds

  Working Principle

  Driven by high-speed CNC spindle, the drill performs axial feed drilling. Its internal coolant channels deliver cutting fluid directly to the cutting edge, rapidly removing heat and lubricating the drill tip. The straight flute design effectively controls chip flow, reduces residue buildup.
