## Long description

Irwin twist drill bit model 10502231 is a single-piece spiral drill with a 1.2 cm diameter intended for general drilling tasks. Compatible with standard drill chucks, this twist bit cuts a clean circular hole in a range of common materials when used at appropriate speeds and with proper support. It is suitable for workshop and construction use where a 12 mm bore is required and fits typical hand and powered drills.
Advantages
The twist geometry provides consistent chip evacuation and stable tracking for straight holes. As a single-piece design, the bit offers reliable concentricity and reduced vibration compared with multi-component tooling. It is suited to a variety of materials including sheet metal, wood, and plastics while maintaining cutting performance across common drilling applications. When applied to stainless steel, care with speed and lubrication improves tool life.
Suitable for
 General workshop drilling in wood and plastics
 Drilling holes in sheet metal and thin metal panels
 Construction site tasks requiring a 12 mm hole
 Maintenance and repair tasks with standard drill chucks
Key specifications
 Type: Twist (spiral) drill bit
 Diameter: 12 mm (1.2 cm)
 Supply: single piece
 Compatibility: standard drill chucks
 Typical materials: sheet metal, wood, plastics; applicable to stainless steel with coolant
How to use
Secure the drill bit in the chuck of a hand or bench drill, ensuring firm tightening and correct centring. Select an appropriate rotational speed for the material—lower speeds for metals, higher speeds for wood and plastics—and apply steady feed pressure. For metal drilling, use cutting fluid or coolant and peck drilling on deeper holes to clear chips. After use, clean the flutes of chips and store the bit in a dry place to prevent corrosion.
Usage recommendations
For sheet metal and general-purpose work, this twist drill performs well at moderate speeds. When drilling stainless steel, reduce cutting speed and use a suitable coolant to minimise heat and prolong tool life. Avoid excessive side load and ensure workpiece clamping to maintain hole accuracy and reduce risk of breakage.
