Precision-max Step Point 12.0mm Hss Dril 5 Pack

Features

• 12.0 mm diameter — suited for medium structural and clearance hole drilling.
• Step-point tip — helps maintain centering and reduce walking at startup.
• Split point geometry — lowers thrust and aids in cleaner entry edges.
• Tri-flat shank — resists slippage under torque load.
• Fully ground spiral flutes — for smooth chip removal and minimized friction.
• Industrial HSS construction — built for durability and consistent performance.

Benefits

• Better starts: tip geometry helps reduce walking and ensure accurate hole positioning.
• Consistent results: matched bits in the set maintain uniform performance over changes.
• Reduced tool downtime: backup bits in pack allow continuous workflow without interruption.
• Wide application: useful for structural, metal, plastic, composite panels and workshop tasks.

Extra Information

• Use appropriate cutting fluid in steel to protect bit life and surface finish.
• Start with moderate speed and feed; avoid applying excessive force, which can deflect or deteriorate accuracy.
• Support thin materials with backing when drilling to prevent exit burr or breakout.
• For deep holes, retract periodically (peck drilling) to clear chips and cool the bit.

Specifications

Safety

• Wear eye protection — chips and fragments may eject at high speed.
• Secure the workpiece firmly — avoid drilling by hand on small parts.
• Use steady feed pressure — avoid side force or tweaking the bit.
• Manage heat — use coolant, breaks or step-down feeds for harder materials.
