6 Pack Titanium Coated HSS Twist Drill Bits, 3-8mm Hex Shank Serrated Cutting Drill Bit Serrated Grooving Cuttings Carpenter Side Cutting Tap for Metal Wood Plastic Drilling and Cuttings

• Package Contents: You will receive 6 side cutting drill bit in sizes of 3mm, 4mm, 5mm, 6mm, 6.5mm, and 8mm, comprehensively covering drilling needs from fine to general applications.
• High-Speed ​​Steel Material: The serrated side cutting drills bit are made of high-quality high-speed steel (HSS) with a robust titanium coating. This process not only greatly enhances hardness and wear resistance but also ensures a consistently pointed cutting edge, easily performing as a high-performance side cutting drill bit for wood, plastic, and soft metals. If you need reliable side cutting drill bits for metal like aluminum alloys, these serrated drill bits deliver clean, fast results.
• Helical Flutes Design: The spiral saw drill bit optimized precision helical flute structure effectively reduces friction and heat buildup, achieving rapid heat dissipation. Simultaneously, the smooth chip removal channel ensures smooth chip removal, resulting in clean, smooth holes and significantly reducing burrs and workpiece breakage.
• Straight Shank Design: These titanium twist cutting bits feature a hex shank design for excellent clamping force and operational stability. Designed as heavy-duty side cutting bits and versatile twist drill bits, they prevent slippage, providing excellent clamping force and operational stability, effectively preventing slippage or deflection during startup. Combined with a pointed center locating tip, precise positioning is achieved, ensuring every drill begins accurately and ends efficiently.
• Enhanced Workflow: Whether for home DIY, model making, or appliance repair, this multi-size hole drill bit is your indispensable tool. Its efficient chip removal and pointed cutting edge can significantly improve drilling speed and overall work efficiency, making the operation process smoother and less labor-intensive.
