Product description
Tork Craft Precision-Max Step Point Drill — 4.2 mm HSS (1 Piece)
Achieve precise, clean holes with this 4.2 mm high-speed steel drill bit. Its step-point (stepped spiral) design, split point and tri-flat shank reduce walking and slipping, giving you better control and finish on mild steel, stainless, aluminium and plastic.
Features
Features
- 4.2 mm diameter — ideal for precision work and pilot holes.
- Stepped spiral tip (step-point geometry) — helps reduce walking at startup.
- Split point design — aids in self-centering and clean entry.
- Tri-flat shank — prevents slippage in the chuck for better torque transfer.
- Material: M2 High Speed Steel / Tungsten-Molybdenum HSS grade.
- Fully ground flutes for smoother cutting.
- Tip angle: approximately 135° for better centering and reduced burrs.
Benefits
- Accurate starts: Step point and split point minimize drifting and improve entry alignment.
- Better grip in chuck: Tri-flat shank means less slipping under torque.
- Cleaner finishes: Reduced burrs and smoother edges in metals and plastics.
- Versatile use: Suitable for mild steel, stainless steel, aluminium and plastic work.

Extra Info
Extra Information
- Use cutting oil or lubricant when drilling steels to reduce friction and extend bit life.
- Start with moderate RPM (especially in stainless) and feed gently to avoid chattering or breakage.
- Support thin sheet materials with backing to reduce exit burr or breakout.
- Inspect bit regularly; resharpen if edges dull to maintain precision.
Pro Tip
- Use peck cycles (withdraw bit periodically) in deep holes to eject chips and manage heat.
- Rotate drilling direction or re-index if working on composite or layered materials for cleaner exits.
Safety
Safety
- Wear eye protection — chips or fragments may eject during use.
- Secure the workpiece properly — never hold by hand during drilling.
- Do not force the bit laterally — allow cutting edges to do the work.
- Manage heat — pause or reduce feed if the workpiece or bit gets hot.
