Precision-max Step Point 8.0mm Hss Drill Ind. 1pce

Features

• 8.0 mm diameter — ideal for larger pilot holes or through-holes in metal or plastic.
• Step-point tip geometry — promotes accurate starts and reduced drift.
• Split point design — helps the bit to self-center and reduces thrust force.
• Tri-flat shank — resists slippage in the chuck for better torque transfer.
• Fully ground spiral flutes — smooth cutting and efficient chip removal. (Toolcraft spec) :contentReference[oaicite:0]{index=0}
• Tip angle approx. 135° ± 2° — balanced for general-purpose drilling. (Toolcraft spec) :contentReference[oaicite:1]{index=1}
• Suitable for industrial use in metal, plastic and mixed sheet materials. :contentReference[oaicite:2]{index=2}

Benefits

• Reliable start: The step-point + split point combination reduces walking on smooth surfaces.
• High control: Tri-flat shank prevents rotation slip under load.
• Cleaner finish: Sharper entries and cleaner edges, especially in metals.
• Versatility: Suitable for a wide range of materials — steel, aluminium, plastics, composite sheets.

Extra Information

• Use cutting fluid when drilling ferrous metals to reduce heat and wear.
• Start at moderate RPM and feed; avoid forcing the bit, especially in harder materials.
• Support thin stock with backing to reduce exit burr and breakout.
• Periodically retract bit (peck drilling) in deeper holes to evacuate chips and cool the bit.

Specifications

Safety

• Wear eye protection — metal chips and fragments may fly during drilling.
• Secure the workpiece in a vice or clamp — avoid holding small parts by hand.
• Apply steady feed pressure; avoid forcing the bit sideways.
• Allow the bit to cool or pause if material or bit becomes excessively hot.
