Drill bit set Irwin 10502326 — 5 pieces, suitable for drilling, max diameter 9.5 mm

Irwin 10502326 is a 5-piece drill bit set intended for general drilling tasks. The set includes five precision ground bits with a maximum diameter of 9.5 mm and a length of 125 mm, supplied in compact Quadro Pack packaging for convenient storage and transport. Designed with a universal 118° point and ground flutes, these bits deliver accurate centring, efficient chip removal and a clean finish when used in compatible drills.

Advantages

Manufactured to DIN 338 standards, each bit features precision ground cutting edges and ground flute geometry that promote fast drilling and reliable hole quality. The cylindrical shank ensures secure clamping in standard chucks, while the universal point shape makes the set suitable for a variety of common materials. The compact packaging protects the tools and simplifies handling on the job site or in a workshop.

Suitable for

• Drilling holes in wood for joinery and fittings

How to use

Select a drill bit of the required diameter and insert the cylindrical shank into the drill chuck, tightening securely. Use an appropriate drilling speed for the material: lower speeds for soft metals and plastics, medium to high speeds for wood. Apply steady pressure and allow the bit to clear chips periodically; for metals and plastics, use cutting fluid or coolant as needed to reduce heat and prolong bit life. After use, clean chips from the flutes and store the bits in their pack to protect cutting edges.

Usage recommendations

For best results, match drill speed and feed to the material and maintain firm, steady pressure. When drilling metals or plastics, consider light lubrication to improve finish and extend tool life. Replace bits that show excessive wear or chipping to maintain hole accuracy.
