Drill bit Irwin HSS for metal, parabolic point, 19 mm, model 10502415

Irwin HSS metal drill bit with a parabolic point, 19 mm diameter, designed for precise drilling of steel and other metals. Manufactured from high-speed steel (HSS), this 19 mm bit offers wear resistance and consistent cutting performance for through-holes and clearance holes in metalworking, fabrication and maintenance applications. The parabolic (undercut) point geometry helps with chip evacuation and reduces walking at the start of the hole, making it suitable for use in hand-held drills and drill presses when accurate 19 mm holes are required.

Advantages

The HSS material provides heat resistance and durability under sustained cutting conditions. The parabolic point improves centring and chip removal, reducing clogging and heat build-up during drilling in steel and non-ferrous metals. A 19 mm diameter offers a common size for clearance and through-holes in structural and mechanical assemblies. The bit is compatible with standard drill chucks used on both portable drills and bench drills, enabling versatile use across workshop and maintenance environments.

Suitable for

• Drilling through-holes and clearance holes in steel plates and metal components
• Fabrication and assembly work in workshops and industrial settings
• Maintenance and repair tasks requiring accurate 19 mm holes
• Use with hand drills and drill presses for metalworking

Key specifications

• Material: high-speed steel (HSS)
• Tip geometry: parabolic / undercut point for improved chip evacuation
• Diameter: 19 mm
• Typical applications: drilling steel and other metals, clearance and through-holes
• Compatibility: suitable for standard drill chucks on hand-held drills and drill presses

How to use

Secure the 19 mm Irwin HSS drill bit in the drill chuck so the shank is fully seated and tightened. Mark the drilling point on the workpiece and, if necessary, create a small centre punch dimple to prevent walking. Use appropriate cutting speed and feed for HSS in metal: lower speeds for harder steels and moderate speeds for softer metals. Apply cutting fluid or coolant for improved lubrication and chip evacuation when drilling steel. Withdraw the bit periodically on deep holes to clear chips and reduce heat build-up.

Usage recommendations

For best results when drilling steel, use a suitable cutting fluid, maintain steady feed pressure, and select drill speeds compatible with the material hardness. Always wear appropriate eye and hand protection and secure the workpiece before drilling.
