Broaching tool & spare blades

For very hard materials with hardness gretaer than 30 HRC or 300 Vickers it is necessary to pre-broach the slot for the kees. The first step is to mark the position of the kees on the parent material. To do this wind the keenseerts in until the kees touch the surface of the parent material.

Mark the positions of the kees and unwind the keenserts.

Then line up the blades of the broaching tool with the marked positions and push it in with a hammer or under a press, remove the broaching tool and install the keenserts.

In somes cases it may be necessary to run the tap back down the hole to clear out any burrs.

Available for external metrical thread M5 and up and external imperial thread 1/4" and up.
