Drill Bit Irwin 10502489 — hardened steel, for drilling

Irwin 10502489 is a hardened steel drill bit designed for general-purpose drilling in metal and other common workshop materials. The bit combines a hardened-steel construction with a geometry intended to provide reliable cutting performance and extended service life under typical workshop and construction conditions. Its retail-friendly packaging and compact dimensions make it easy to store and transport.

Advantages

The hardened steel composition increases wear resistance compared with untreated bits and supports consistent drilling performance across multiple work sessions. The bit’s geometry promotes efficient chip removal and stable drilling, reducing the risk of wandering and breakage. Its durable construction makes it suitable for repeated use in hand-held drills and drill presses.

Suitable for

• Drilling holes in mild and medium-hard metals
• General workshop and maintenance tasks
• Construction site drilling where a robust steel bit is required
• Use in portable drills and bench drills for routine fabrication

Key specifications

• Material: hardened steel for improved wear resistance
• Intended use: general drilling applications
• Compatibility: suitable for use in hand-held drills and drill presses
• Packaging: retail-ready dimensions for easy storage and display

How to use

Secure the drill bit in the chuck of a suitable drill so it is centered and tightened. Select an appropriate drill speed and apply steady, moderate pressure while drilling to maintain control and reduce heat buildup. For metal drilling, use cutting fluid or coolant to prolong bit life and improve chip evacuation. After use, clean chips from the flutes and store the bit in dry conditions to avoid corrosion.

Usage recommendations

Use the bit with correct speeds and lubrication for the material being drilled; avoid excessive side loads and abrupt impacts to preserve cutting edge integrity and extend service life.
