Key features

• Upgraded Ball Bearing Aluminum Alloy Stop CollarAluminum alloy collar with precision ball bearings halts rotation instantly on wood contact. Prevents over-drilling and friction burns, cutting wood wear by up to 90% versus traditional collars.
• TCT Cutter + HSS M2 Pilot BitsTCT (tungsten carbide-tipped) cutters are 30% sharper than regular carbon steel, delivering clean, chipping-free cuts. HSS M2 pilot bits offer high toughness, resist bending and breaking for stable drilling. The combined structure ensures steady performance and great service life.
