TORK CRAFT PRECISION-MAX STEP POINT 3.5mm HSS DRILL IND. 1Pc
Make precise pilot and clearance holes with a 3.5 mm high-speed steel bit featuring step-point geometry that starts true and resists walking. Ideal for mild steel, aluminium, plastics and thin laminates where clean entry and accurate positioning matter.
Features
- 3.5 mm diameter — handy size for pilot holes and small fasteners.
- Step-point tip — self-centering to minimise wandering and produce cleaner entries.
- HSS construction — durable balance of hardness and toughness for general workshop use.
- Straight shank — compatible with standard 3-jaw chucks on hand drills and drill presses.
- Sold as a single bit for replacements or top-ups.
Benefits
- Cleaner holes: reduced burrs on entry, especially in thin sheet.
- Better control: self-centering geometry often removes the need for a centre punch.
- Versatility: suitable for mild steel, aluminium, brass, plastics and laminates.
- Efficient drilling: quicker start reduces setup time and rework.
Extra Information
- Use appropriate cutting/lubrication when drilling metals (e.g. cutting oil on steel) to extend bit life.
- Start slow, especially on harder metals; ramp up speed as the hole progresses.
- Use pilot drilling or pecking cycles for deeper holes to clear chips and avoid overheating.
- Inspect bits after use; resharpen or retire if edges become chipped or dull.
Pro Tip
- For stainless or harder alloys, slow the RPM and use consistent lubrication to prevent work-hardening.
- Peck drill (periodically withdraw to clear chips) on deeper holes to manage heat and swarf.
