Tork Craft Countersink 12mm HSS 90 Degree 5-Flute 1/2″

Specifications:

• High Speed Steel Countersink
• The five flute rose pattern design has been a principle countersink design for over 100 years
• The odd number of flutes reduces chatter on steel, brass and aluminium
• Also used for plastic and wood application
• A common use is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material
• A countersink may also be used to remove the burr left from a drilling or tapping operation thereby improving the finish of the product and removing any hazardous sharp edges
• Regardless of the name given to the cutter, the surface being generated may be a conical chamfer (plunging applications) or a beveled corner for the intersection of two planes (traversing applications)
