Changeable-Blade Ratcheting Deburring Scrapers
A ratcheting handle saves space when smoothing the edge of tubes and holes. With short, repeatable turns, these scrapers deburr with greater speed and precision than standard scrapers.
The length of the scraper is adjustable—shorten it to work closer to the tube or hole, and lengthen it to deburr edges that are farther away. Replace the blade when it's dull, or change it out for another blade style to complete different tasks.
Use scrapers for front hole edges on holes that are drilled into metal and plastic parts.
Scrapers for outer tube edges wrap around the end of tubes and rods up to 1" in dia.

Hex-Shank High-Speed Steel Countersink Sets for Screws
Choose countersinks of different sizes from these sets. Compared to countersinks with round shanks, these 1/4" hex-shank countersinks can be gripped more tightly by compatible drills and screwdrivers for greater torque. These countersinks cut at 90° angles suitable for metric flat-head and oval-head screws, and are also good for deburring holes or smoothing edges. Made from high-speed steel, use these on most metal and plastic.
