Black oxide coating for longer life on replacement drill bits with countersinks; split point drill bits start on contact and minimizes bit walk.
General Tools Countersink Bit, Rose Pattern, 1/2 in Pilot Diameter, 5 Flutes, 82 deg, 1/4 in Shank, Stepped, Round Shank, High Speed Steel Cutting Edge, Applicable Materials: Steel, Brass, Aluminum, Plastic and Wood, For Finishing The Woodworking Project and Useful in Making Furniture, Cabinets, Shelves and Small Wood Projects
Multi cutter countersinks for superior finish in applications such as deburring and chamfering in iron, steel, soft metal, plastic, wood and other machine-able materials. Black oxide split-point drill bits start on contact.
Tapered drill with widened flutes for drilling fast, clean pilot holes. 1/4" quick change shank reduces slipping in standard chucks and is compatible with all 1/4" quick change chucks, including impact drills. Adjustable four-cutter counterbore cuts and clears chips quicker for fast, smooth countersinking. Counter bore attaches to flats on shank with two hex screws for a secure fit and can be adjusted for controlled pilot hole depth.
Drill, countersink and counterbore in one step. Four-cutter countersink and tapered drill bit provide speed and finish.
Precision ground 82 degree tip for countersinking most machinable metals, wood or plastic. High speed steel with black oxide coating for corrosion resistance. 5 flute design reduces chatter for smoother drilling and extended life.
High speed steel milled and precision ground to 82 degrees for countersinking into most machinable materials such as iron, steel, soft metals, plastic or wood.
