## Summary description

Irwin twist drill bit model 10502563 with a 9 mm diameter, supplied as a single piece. Designed for drilling applications with standard twist-drill geometry to cut holes in common materials. Suitable for manual and powered drills for general-purpose drilling tasks in metal, wood or plastics depending on material compatibility.

## Long description

Irwin twist drill bit model 10502563 — 9 mm, single piece is a high-speed steel (HSS) cobalt twist drill designed for general-purpose and heavy-duty metal drilling. With a 9 mm cutting diameter and a cylindrical shank, this single-piece bit follows standard DIN 338 geometry and a 135° split point to reduce walking and improve centring when starting holes. The construction includes a reinforced web and cobalt alloy suitable for increased heat and abrasion resistance, making the bit appropriate for demanding drilling tasks in various metals and other compatible materials.
Advantages
The 5% cobalt composition provides improved hardness at elevated temperatures and greater wear resistance compared with conventional HSS bits. The heavy-duty web construction enhances strength and reduces the likelihood of breakage under load. The 135° split point geometry starts drilling immediately with less applied pressure and better hole accuracy. Manufactured to DIN 338 standards, the bit offers consistent concentricity and reliable performance for repeatable drilling results.
Suitable for
Drilling holes in alloyed steels and hardened metals
General metal fabrication and repair work
Workshop and site use with hand-held or bench drills
Drilling stainless steel and other tough materials where higher heat resistance is required
Key specifications
Drill type: Twist drill bit, HSS cobalt construction (approx. 5% cobalt)
Diameter: 9 mm
Overall length: 125 mm
Point angle and geometry: 135° split point
Shank type: Cylindrical shank
Quantity: 1 piece
How to use
Clamp the cylindrical shank securely in the drill chuck and set the drill speed appropriate for the material being drilled. For metals, use moderate speed with steady pressure, applying cutting fluid or coolant as needed to reduce heat and extend bit life. Start with a centre punch or pilot mark to prevent walking, then engage the split point and maintain a consistent feed until the hole is completed. Clear chips periodically to avoid clogging and overheating.
Usage recommendations
Use the bit with appropriate cutting fluid for stainless and alloyed steels, select lower speeds for hardened materials, and avoid excessive side-loading. Store the bit dry and protected to preserve cutting edges and prevent corrosion.
