Tork Craft Drill Bit — HSS 15.5 mm Reduced Shank
A durable 15.5 mm drill bit made from high-speed steel (HSS), featuring a reduced shank so that a larger cutting diameter can be accommodated by chucks with lesser grip capacity. Excellent for heavy fabrication, metalworking and general workshop tasks.
Features
- Cutting diameter: 15.5 mm
- Reduced shank for compatibility with smaller chucks
- High-speed steel (HSS) construction for toughness and wear resistance
- Twist flute geometry for effective chip removal
- Carded single unit (1 per card)
Benefits
- Use large-diameter bits in smaller chucks by means of the reduced shank
- Strong performance in metals, composites, plastics and general materials
- Stable, aligned cutting even at increased diameters
Extra Information
- Ensure the chuck grips the reduced shank section fully to avoid slippage
- Use appropriate speeds and feeds, especially in harder materials
- Clear chips regularly during deep drilling to maintain cutting efficiency
Pro Tip
- Start with a center punch to guide the bit into position and prevent wandering
- Check for run-out after mounting — small misalignment becomes more significant at larger diameters
