4 flute wood boring bit Diameter: Ø12.0mm Overall length: 400mm Shank: 6.35mm hex for quick change Application: Use the 4 flute boring bit to drill into wood/timber. A low rpm rotary drill with a planetary gearbox is required to be used with boring bits. It is possible to use a cordless drill, but in its lowest gear. Benefits: The drill spurs have 4 cutting edges that leaves a cleaner and more precise bored hole. Using the same designed screw tip as from an auger drill bit - the 4 flute boring bit feeds itself. The shank can be clamped into a 6.35mm quick change chuck or a standard 3 jaw chuck. It also prevents slipping in a chuck. The edges of the bit have been hardened and remains sharper for longer. The flutes are designed to have excellent chip/shaving clearance. 4 cutting edges means faster cutting and more durability. CAUTION: Take care when drilling with wood boring bits. Keep the rotary drill steady with both hands to prevent wrist injury.
