Drill bit Irwin 10502229 twist drill bit Ø10 mm, 1 pc

Irwin 10502229 is a single twist drill bit with a 10 mm diameter designed for general-purpose drilling with hand or machine drills. The steel construction and standard helix geometry make this bit suitable for drilling through wood, plastic and various metals, while the supplied single piece fits chucks that accept its shank form. With an overall length of 133 mm and a triangle shank for slip-resistant mounting, this drill bit is sized for common repair, assembly and construction tasks where a reliable 10 mm hole is required.

Advantages

The twist geometry provides stable cutting action and effective chip evacuation for a range of materials. Steel construction offers durability for routine use, and the 10 mm diameter delivers a standard hole size for fittings and fasteners. The triangle shank improves grip in chucks that accept non-round shanks, reducing slippage during drilling. Supplied as a single unit, the bit is ready for immediate installation in compatible drills.

Suitable for

• Drilling holes in wood for joinery and carpentry
• Drilling plastic components and panels
• Light to medium drilling in sheet metal and non-hardened steel
• Repair and maintenance tasks requiring a 10 mm bore
• Assembly work for installing fasteners and fittings

Key specifications

• Type: twist drill bit
• Diameter: 10 mm
• Overall length: 133 mm
• Shank type: triangle shank
• Material compatibility: wood, plastic, sheet metal, stainless steel (use coolant for stainless steel), general metals

How to use

Install the drill bit into a compatible drill chuck that accepts a triangle shank and tighten securely. Select a suitable rotation speed and feed rate according to the material being drilled: lower speeds and light pressure for metals, higher speeds for wood and plastic. For metals and stainless steel, use cutting fluid or coolant and peck-drill where appropriate to manage heat and chip removal. After drilling, clear chips from the hole and inspect the bit for wear before reuse.

Usage recommendations

Use protective equipment such as safety glasses and gloves. For stainless steel drilling, apply coolant continuously and consider using appropriate HSS cobalt drills for prolonged or heavy-duty stainless applications. Replace the bit if signs of chipping or excessive wear appear to maintain hole quality and safety.
