Spade Drill Bit Irwin 10502808 — 14 mm Diameter

Irwin spade drill bit 14 mm diameter is designed for rapid drilling of soft and construction woods with handheld drills and drill drivers. The flat spade tip and BLUE‑GROOVE point enable fast chip evacuation and straightforward hole formation, while double cutting spurs score the outside of the hole to reduce breakout. The bit features a thicker cutting edge for extended life and an enlarged shank for improved durability; it accepts 1/4" quick‑change chucks for fast bit swaps.

Advantages

The spade geometry and BLUE‑GROOVE point deliver fast drilling speed and efficient chip removal, reducing clogging during through‑holes in timber. Double cutting spurs improve edge quality by scribing the workpiece perimeter and minimizing tear‑out on the exit side. A thicker cutting edge increases wear resistance for longer service life, and the 10% larger shank and 1/4" quick‑change compatibility enhance stability and make bit changes quicker in cordless drivers and impact‑ready quick‑change adapters.

Suitable for

• Fast through‑hole drilling in softwood and construction timber
• Carpentry and framing tasks requiring repeated hole production
• Electrical and plumbing installations for running cables and pipes through studs
• On‑site work with handheld drills and quick‑change chucks

Key specifications

• Cutting diameter: 14 mm
• Tip type: flat spade with BLUE‑GROOVE point
• Edge features: double cutting spurs and thicker cutting edge
• Shank: enlarged shank for added durability, compatible with 1/4" quick‑change holders
• Primary use material: softwood and construction timber

How to use

Secure the spade drill bit in a 1/4" quick‑change chuck or compatible drill holder, ensuring it seats fully to maintain concentricity. Mark the hole position on the timber and, where practical, clamp the workpiece. Start drilling at low speed to engage the spade tip, then apply steady pressure and increase speed as the bit clears wood chips; the BLUE‑GROOVE point helps evacuate chips while the double spurs reduce breakout. Withdraw the bit periodically for deep holes to clear chips and prevent overheating.

Use sharp, undamaged bits for best results; for cleaner exit holes, back the workpiece with sacrificial wood or drill from both sides when precision finish is required. Keep the bit cool and remove accumulated chips to prolong cutting life.
