## Summary description

Irwin Twist drill bit, model 10502559, 7 mm diameter, single piece. Designed for drilling operations with standard drills for metal, wood and plastic depending on drill speed and feed. Straight-shank twist design provides axial stability and chip evacuation. Suitable for repair, assembly and general-purpose drilling tasks.

## Long description

Irwin Twist 7 mm drill bit is a single-piece, straight-shank HSS cobalt twist bit designed for general-purpose and heavy-duty drilling. Made with 5% cobalt and a robust web construction, the bit provides increased heat and abrasion resistance for demanding metalworking tasks. The 135° split point reduces walking at startup and improves centring, while the twist flute geometry ensures efficient chip evacuation and stable axial performance across metal, wood and plastic when used with appropriate speeds and feeds.
Advantages
This 7 mm HSS cobalt drill bit offers improved performance in high-temperature and abrasive conditions due to its 5% cobalt composition. The heavy-duty web increases strength and durability for extended tool life under load. A 135° split point provides quick penetration and reduced bit wandering, enabling more accurate hole placement. The straight-shank twist design promotes reliable chip removal and stable drilling action in a range of materials when matched with suitable drilling parameters.
Suitable for
 Drilling holes in various metals, including hardened and heat-treated alloys
 General repair and assembly work in workshops and maintenance settings
 Drilling in softer materials such as wood and plastics with adjusted speed
 Use with standard handheld and bench drills for precision and repeatability
Key specifications
 Cutting diameter: 7 mm
 Material: high-speed steel with 5% cobalt
 Point angle and geometry: 135° split point for reduced walking
 Shank type: straight shank suitable for standard chucks
 Flute design: twist flutes for chip evacuation and cooling
 Standards: manufactured to DIN 338 dimensional and performance principles
How to use
Secure the drill bit in the chuck of a handheld or bench drill ensuring the shank is properly seated and tightened. Select an appropriate speed and feed for the material being drilled: lower speeds for hard or heat-treated metals and higher speeds for wood or plastics. Apply steady axial pressure, allowing the bit to cut without excessive force. Periodically withdraw the bit to clear chips and reduce heat buildup. For metal applications, consider using a suitable cutting fluid to improve tool life and surface finish.
Usage recommendations
Use personal protective equipment such as safety glasses and gloves. Avoid overheating by using correct speeds and by applying cutting lubricant when drilling metals. Store the bit in a dry place and protect the cutting edges from contact with harder surfaces to preserve performance.
