Precision-max Step Point 12.0mm Hss Drill Ind. 1pce

Extra Information

• Use cutting fluid or oil when drilling ferrous metals to reduce friction and extend bit life.
• Use a moderate feed and speed; avoid forcing the bit, especially in harder materials.
• Support thin or curved materials with backing to minimize exit burr or break-through.
• For deeper holes, retract periodically (peck drill) to clear chips and manage heat.

Features

• 12.0 mm diameter — suitable for medium bore applications and structural hole work.
• Step-point geometry — helps improve centering and reduce drift at startup.
• Split point tip — reduces thrust requirements and enhances edge sharpness.
• Tri-flat shank — helps prevent slippage in the chuck under torque.
• Fully ground spiral flutes — promote better chip ejection and lower friction.
• Robust industrial HSS construction for durability and service life.

Benefits

• Better starts: The combined geometry reduces walking and helps maintain precise entry alignment.
• High control: Tri-flat shank minimizes spin-out under load.
• Cleaner results: Sharper entry and smoother holes in metals and plastics.
• Broader application: Suited for structural drilling, fabrication, and general workshop tasks.

Safety

• Wear eye protection — chips or fragments may eject at high speed.
• Secure workpiece firmly — avoid drifting or slipping during drilling.
• Maintain steady feed pressure; avoid forcing the bit sideways.
• Use coolant or intermittent breaks to manage heat in tougher materials.
