CNC Countersink Depth Stop Tool
Spring Loaded to Countersink Uneven Surfaces

Control Countersink Depth in 0.001″ Increments with the CNC Countersink Depth Stop Tool

CNC Countersink Depth Stop Tool – Precisely Control Countersink Depth

The CNC Countersink Depth Stop Tool maintains precise countersink depth control on materials with tolerance variations.

Easily control the depth of cut in 0.001″ increments.

Spring loaded design produces accurate countersinks by accommodating for uneven surfaces.

Low friction, soft replaceable Plastic Nosepiece reduces potential marring of the surface of the workpiece.

Hold Countersinks with cutter diameters up to 7/8″.

Popular for use in CNC Machines, Robot Assembly Lines, and other automated equipment.

  • Spring compresses up to 0.375” to compensate for material variations.
  • Fits into a standard 1/2” Collet or End Mill Holder.
  • Accommodates Countersinks with cutter diameters up to 7/8” (0.875” – 22 mm).
  • Hold Countersinks with lengths of 2.0” – 3.0” OL (other tool lengths may be used by changing the replaceable plastic nosepiece).
  • The bearing system is shielded to protect against coolant, chips, graphite and composite material dust.
  • Large cut outs in housing for chip clearance.

*The CNC Countersink Depth Stop Tool is covered by U.S. Patent 7,607,871.

Operating Notes:

  • Spindle speed operation range: 50-500 RPM.
  • Maximum recommended spindle speed: 2,000 RPM.
  • Use slower speeds and a Countersink Tool Bit with Pilot to minimize cutting tool chatter.
Complete Details:

The CNC Countersink Depth Stop maintains precise countersink depth control on materials with tolerance variations.

  • Depth of cut can be adjusted in 0.001” increments.
  • Spring compresses up to 0.375” to compensate for material variations.
  • Tool shank fits into a standard 1/2” Collet or End Mill Holder.

CNC Countersink Depth Stop Tool Holds a Wide Range of Countersink Sizes.

  • Collets that hold Countersink Tool Bits are purchased separately.
  • Collet sizes available: 1/4″, 5/16″, 3/8″, 1/2″, or 5/16″.
  • Accommodates Countersink Tool Bits with cutter diameters up to 7/8” (0.875”/22 mm).
  • Hold Countersinks with lengths of 2.0” – 3.0” OL.
  • Other tool lengths may be used by changing the Replaceable Plastic Nosepiece.
  • 3/8″ Adapter (Part # 11565) is also available, which can be used to hold Standard Threaded Aerospace Countersinks.

Plastic Nosepiece minimizes any potential surface damage to the workpiece.

  • The replaceable Plastic Nosepiece uses a unique bearing design that reduces marring of the workpiece.
  • As the tool touches the material, the Nosepiece stops spinning, which eliminates the potential for surface damage.
  • Nosepiece OD = 1.24” (31 mm).

Controls chips and dust.

  • The bearing system is shielded to protect against coolant, chips, graphite and composite material dust.

Springs apply pressure to the Countersink Tool Bit.

  • Each Countersink Tool includes a Heavy Tension Spring.
  • Use the heaviest spring possible for your application.
  • Use lighter springs for fragile materials that may deform from force.
  • The Extra Heavy Spring reduces the overall travel to approx. 0.250″.

Use 2L Solid Carbide Countersink Tool Bits for maximum tool life and chatter reduction.

Each CNC Countersink Tool Includes:

  • CNC Countersink Depth Stop Tool with 1/2″ diameter shaft.
  • – Heavy Spring, Part No.: 10707.
  • – Hex Wrench, Part No.: 10197.
  • – Plastic Nosepiece, Part No.: 11543.

Use the CNC Countersink Depth Stop Tool with:

  • CNC Machines.
  • Routers.
  • Robots and many other applications.
