JNB Countersink Set for Metal - 5 Pc, 82-Degree HSS-Co
A 5-piece countersink set engineered for metal. Made from High-Speed Steel with 5% cobalt (HSS-Co, M35 grade) for exceptional durability and heat resistance, these bits chamfer pre-drilled holes in hard and soft metals as well as wood. The 5-flute, 82-degree design reduces vibration for smoother cuts and cleaner finishes.
A Black & Gold corrosion-resistant coating extends tool life, and the 1/4" round shank fits both stationary and handheld drills. Note: these are chamfer tools, not self-drilling - drill a pilot hole sized to your screw before countersinking.
Specifications: 5-piece metal countersink set; HSS-Co (M35, 5% cobalt); 5-flute 82-degree design; Black & Gold coating; 1/4" round shank; for pre-drilled holes (not self-drilling).
