Drill bit Irwin HSS spot-faced for metal 14.5 mm (model 10502406)

Irwin HSS spot-faced drill bit with a 14.5 mm diameter is designed for metalworking tasks that require both drilling and creating a flat, recessed face around holes. Manufactured from high-speed steel (HSS), this spot-facing bit is intended to withstand the cutting speeds and heat generated when working with ferrous and non-ferrous metals. The bit’s geometry combines a pilot drilling feature with a spot-facing rim to produce accurate hole placement and a clean, flat counterbore surface in one step.

Advantages

The HSS construction offers durability and resistance to wear at elevated cutting temperatures, enabling consistent performance when used with appropriate speeds and cutting fluids. The integrated spot-facing design reduces the need for separate countersink or milling operations, saving time and maintaining concentricity between the drilled hole and the finished flat surface. Its 14.5 mm diameter is suitable for medium-size holes and ensures stable contact during spot-facing.

Suitable for

• Spot-facing and drilling operations in mild steel and stainless steel
• Work on aluminum, brass and other non-ferrous metals
• Use with drill drivers and drill presses for workshop and maintenance tasks
• Preparing flat, recessed surfaces for fastener heads and washers

Key specifications

• Material: high-speed steel (HSS)
• Type: spot-faced drill bit combining pilot drill and spot-facing rim
• Diameter: 14.5 mm
• Intended application: metal drilling and spot-facing
• Compatible drive: standard drill chucks on handheld drills and drill presses

How to use

Secure the workpiece and mark the center point for drilling. Fit the bit into a properly rated drill chuck and tighten securely. Select an appropriate rotational speed for the material being machined and apply cutting fluid when recommended to reduce heat and improve tool life. Start drilling with steady axial pressure, allowing the pilot portion to establish the hole, then continue until the spot-facing rim creates the flat recess. Withdraw the bit periodically to clear chips and inspect the finished recess for required flatness and diameter.

Usage recommendations

For best results, use coolant or cutting oil when machining harder steels, run the drill at moderate speeds to avoid overheating, and ensure the drill press or handheld driver is stable to maintain concentricity. Replace the bit if wear or chipping affects surface finish or drilling accuracy.
