3/32 Carbide Drill Bit for Hardened Steel Aluminum Metal Solid Tungsten K20 Carbide Drill Bit by YFTOOL 5pcs

Key features

• MAX 1000 Holes: Suitable for industrial or reusable drilling of materials with a hardness below HRC55, such as hard steel, aluminum, copper, mild steel,tool steel and carbon steel. A maximum of 1000 holes can be achieved depending on the working conditionsrequire.
• Suitable for high-precision and stable hole machining on CNC machines or drill presses, and featuring good cooling and effective coolant to extend drill bit life. Not recommended for use with any hand tools.
• YFTOOL Carbide Drill Bit | Precision For Delicate Work：this solid carbide drill bit set includes 1/4" drills, engineered for fine and precise drilling. the premium carbide construction ensures exceptional rigidity, guaranteeing tight tolerances within ±0.003mm for demanding applications
• TiALSi coating：TiALSi coated carbide drill bit isa specialized solution for high-productivity drilling in soft tomedium-strength ductile materials,where preventing material adhesionand achieving high feed rates arecritical
• K20 Carbide：the foundation of this carbide drill is a k20 grade carbide with an ultra-fine 0.3-micron grain structure. this delivers two key benefits: extreme wear resistance for a longer tool life and superior strength/rigidity to prevent deflection and breakage, ensuring consistent precision in every cut
