BIT CSINK #10 3/16"HSS

PRODUCT DESCRIPTION:

The Irwin 1882783 is a tapered countersink drill bit designed primarily for woodworking. It is intended to drill pilot holes and countersink screws in one operation. It’s part of Irwin’s SPEED-BOR line and is sized for #10 screws. It includes features for faster chip removal and more controlled countersinking.

ADDITIONAL FEATURES:

Combines pilot drilling + countersinking in one pass, saving time.

Good chip clearance due to wider flutes.

Adjustable counterbore lets you set depth, improving finish and preventing over-countersinking.

Quick-change shank and compatibility with impact drills and standard chucks.

INSIGHTS:

Speed & feed: For wood, use moderate to high speeds depending on wood hardness; keep steady, avoid too slow that causes burning. For hardwoods, slower speeds with sharp bit needed.

Pilot hole/check fit: Because pilot hole size is fixed (tapered/corresponding to #10), if screw size or type differs, ensure fit is correct; mismatched screw may split wood or have poor seating.

Maintain sharpness: Keep the cutting surfaces clean, avoid overheating; HSS can be sharpened but you’ll need proper tools / experience.

Storage/care: Dry storage to avoid rust (HSS is susceptible), especially if the finish is not a very protective coating.
