Precision-max Step Point 5.5mm Hss Drill Ind. 1pce

Extra Information

• Apply cutting fluid or lubricant when drilling steel to improve finish and extend bit life.
• Use moderate feed and speed — avoid forcing, which may deflect or break the bit.
• Support thin materials with a backing board to avoid breakout at exit.
• Remove chips in deeper holes by retracting the bit periodically (peck drilling).

Features

• 5.5 mm diameter — suitable for larger pilot holes or medium fasteners.
• Step-point geometry — helps reduce walking and improves entry accuracy.
• HSS material — balanced for durability and performance in general use.
• Straight shank — for compatibility with standard 3-jaw chucks.
• Fully ground flutes — for smoother chip evacuation and reduced friction.
• Tip angle approximately 135° for clean penetration and controlled cutting.

Benefits

• Reliable starts: Step-point tip helps maintain centering even on smooth or coated work surfaces.
• Consistent finish: Reduced burrs and better edge quality in metal and plastic work.
• Versatility: Suitable for mild steel, aluminium, plastics, laminates and composite sheet tasks.
• Efficient drilling: Cleaner starts cut down rework and misaligned holes.

Safety

• Wear eye protection — chips and fragments may be ejected during drilling.
• Secure the workpiece firmly — avoid freehand drilling on small or thin parts.
• Apply steady feed pressure; don’t twist or force the bit sideways.
• Manage heat — use coolant, rest intervals or lower speeds when needed.
