Reduce Chatter While Countersinking, Chamfering & Deburring

Made of submicron grade carbide

2L Countersink Tools with Pilots are designed for countersinking, chamfering or deburring.

Each size may be used on a wide range of hole diameters.  The solid carbide shanks ensure maximum rigidity to reduce chatter.

These Countersinks with integrated pilot drills reduce chattering by allowing the pilot to closely fit into a predrilled hole.

Countersink Tools can be used in a rigid tool holder such as a collet or end mill holder, or with the 2L CNC Countersink Depth Stop Tool.

2L Countersink Tools are made of a premium sub-micron grade of carbide for maximum strength and durability.

If you require different number of flutes, angle or drill diameter for these Piloted Countersinks contact us or, submit a custom tool request.  We produce these tools in house with short production lead times.
