Drill bit set Irwin 10502301 — 10 pieces, 7 mm diameter

Irwin 10502301 is a set of ten 7 mm drill bits designed for professional and DIY drilling tasks. Each bit features a cylindrical shank and a universal 118° point shape that enables clean starts and reliable performance across a wide selection of materials. The bits are precision ground and manufactured to DIN 338 standards, supplied in a Quadro Pack to keep spares organized and accessible for repeated use.

Advantages

The drill bits have precision ground cutting edges and a ground flute profile that deliver fast drilling, efficient chip evacuation, and accurate hole sizing. Conformance to DIN 338 ensures consistent geometry and reliable mechanical properties. The cylindrical shank fits most drill chucks, while the universal 118° point reduces walking and improves centering when starting holes. The package contains multiple identical bits for uninterrupted work when frequent replacement is required.

Suitable for

• General drilling in metal, wood and plastics where 7 mm holes are needed
• Workshop and maintenance tasks requiring multiple identical bits
• Construction and renovation jobs with repetitive drilling operations
• Repair and service work that demands accurate, consistent holes

How to use

Select the 7 mm drill bit and insert the cylindrical shank into the drill chuck, ensuring it is tightened securely. Use appropriate speed and feed for the material being drilled: lower speeds for harder materials and higher speeds for wood and plastics. Apply steady pressure without forcing the bit; allow the cutting edges to remove material and the ground flute to evacuate chips. For improved hole quality, use cutting fluid or lubrication when drilling metals and frequently clear chips to avoid clogging.

Usage recommendations

Inspect bits before use and replace any bit showing wear or damage. Match drill speed and lubrication to the material: use cutting oil for steel, moderate speed for stainless materials, and higher speed for softer materials like wood. Store bits in the Quadro Pack to protect cutting edges and keep spares organized for repetitive tasks.
