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.

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.

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.

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.
