BIT CSINK REP#10 3/16"HSS

PRODUCT DESCRIPTION:

The Irwin 1882789 Replacement Bit is a high-speed steel, tapered countersink / drill bit designed to replace worn or broken bits in the #10 (3/16-inch) wood countersinking systems. It drills pilot holes with a tapered bit and incorporates a counterbore feature to produce a clean recess for screw heads. The bit has widened flutes for fast chip removal, and a ¼-inch quick-change shank so it fits standard quick-change chucks.

ADDITIONAL FEATURES:

Saves time and ensures alignment by combining drilling + countersinking in one tool

Widened flutes improve chip removal, reducing clogging and friction

Quick-change shank improves grip and ease of swapping bits

Replacement bit means you don’t need to replace the entire countersink tool assembly

Good for woodworking tasks needing flush screw placement

INSIGHTS:

Always adjust and lock the counterbore depth before starting work so screws seat flush

Use moderate speed in wood to avoid burning; too fast a feed can cause tear-out

Pull the bit out occasionally to clear chips, especially when working deep holes

When the finish starts to deteriorate (e.g. rough edges, tear-out), sharpen or replace

Keep the bit clean and store dry to prevent corrosion
