BIT DRILL 21/64X2-13/16HS

PRODUCT DESCRIPTION:

The Irwin 60521 is part of Irwin’s general-purpose “605” series of twist-drill bits. It is a fractional size 21/64" jobber-length, straight shank twist drill bit, made of high speed steel with a bright finish. The bit is used for standard drilling tasks in materials like wood, metal, and plastic.

INSIGHTS:

Use moderate speed and steady feed rates, especially when drilling metal, to avoid overheating.

Employ cutting fluid or lubricant when drilling metals to reduce friction and extend bit life.

For deeper holes, use peck drilling to help clear chips.

Prefer a drill press over hand drilling when possible for better alignment and reduced bit wandering.

Keep bits clean and dry to prevent corrosion and damage.
