Domer G2363 HSS TiAIN Countersink Set

Introducing the G2363 Countersink Set from Dormer is an essential accessory for any tradesman. Featuring six pieces to this set for various types of materials and when using screws, bolts or rivets they can provide a flush neat finish. Designed with three flutes per countersink to allow for a better chip clearance compared to four flutes to prevent any clogging from occurring. Every countersink is constructed from High-Speed Steel (HSS) providing exceptional hardness to prevent any wear hardness. In addition to the HSS, a TiAIN coating allows the countersink to maintain the high standard cutting at high temperatures. The coated bits can be operated at speeds up to 100% higher and for longer than uncoated countersink bits.
