Drill bit Irwin 10502413 — twist drill bit, diameter 1.8 cm, 1 pc

Irwin 10502413 is a single twist drill bit with a 1.8 cm diameter designed for general-purpose drilling where a precise, clean hole is required. The bit features precision ground cutting edges, a ground flute for efficient chip evacuation and stable drilling, and a reduced shank that allows use in a variety of chucks. Manufactured to DIN 338 standards with a universal 118° point geometry, this twist drill bit is suitable for handheld drills and drill presses when drilling through plastics, soft metals and wood.

Advantages

The precision ground cutting edges and ground flute provide fast drilling and consistent finishing quality, while the universal 118° point ensures reliable centring and reduced walking on many materials. The reduced shank increases compatibility with different chucks and the solid twist geometry improves chip removal for longer continuous drilling. Compliance with DIN 338 standards guarantees consistent manufacturing tolerances and reliable performance.

Suitable for

• Drilling 1.8 cm holes in plastic components
• Making clearance or pilot holes in soft metals (e.g., aluminium)
• Woodworking tasks requiring a 1.8 cm diameter hole
• Use with handheld drills and drill presses

How to use

Secure the Irwin 1.8 cm twist drill bit in the drill chuck, ensuring the reduced shank is seated and tightened correctly. Select an appropriate rotational speed for the material being drilled: lower speeds for soft metals and higher speeds for wood and plastics. Use steady, moderate feed pressure and allow the bit to clear chips periodically to avoid clogging. When drilling metals, consider using cutting fluid to extend tool life and improve finish. Recheck hole diameter after drilling to ensure accuracy.

Usage recommendations

For best results, match drill speed and feed to the material: moderate speed with cutting lubricant for soft metals, higher speed and light pressure for plastics and wood. Ensure the workpiece is clamped securely and the drill bit is sharp and undamaged before use. Replace the bit if excessive wear or chipping of the cutting edges is observed.
