Counterbores

n Built-in chamfering operation
n Stub length for rigidity
n Three flute spiral design
n High speed steel

Here is a special purpose tool that not only performs its job well, but gives you added tooling performance besides.
The built-in chamfer design automatically allows clearance for the radius under the Ejector Pin Head and insures
proper seating of the pin.
DME Counterbores are hardened and precision ground from top quality high speed steel to give you cleaner cutting
and longer life. The three-flute spiral design has been engineered to reduce tool wear and give faster cutting action
through rapid chip clearance.
DME Counterbores can help make counterboring easier and reduce your tooling costs… and here’s how:
1. Drill the retainer plate to suit your DME Ejector Pin diameter
2. Select the DME Counterbore with the same Item Number as the DME Ejector Pin to be used (*) and counterbore
to the proper depth… And that‘s it!
(*) Example: For an EX17 Ejector Pin or C17 Core Pin, use a CB17 Counterbore.
