Precise parting and slotting on the PD 250/E.

The included HSS cobalt tool measures 12×3×85mm — the cobalt content increases heat resistance and hardness compared to standard HSS, extending tool life during the demanding parting operation. Replacement tools are available separately. What's Included Parting tool holder (for PD 250/E quick-change tool post) 1 HSS cobalt parting tool — 12 × 3 × 85mm Key Specifications Compatible machine: Proxxon Precision Lathe PD 250/E Compatible tool post: PD 250/E quick-change tool post system Tool material: HSS with cobalt (HSS-Co) Tool dimensions: 12 × 3 × 85mm Operations: Parting (cut-off) and slot cutting Part No.: 24217 Why HSS Cobalt for Parting? Parting is one of the most demanding lathe operations — the narrow tool engages the full depth of cut simultaneously, generating significant heat and cutting forces. HSS cobalt (HSS-Co) contains 5–8% cobalt, which increases the tool's hot hardness and wear resistance compared to standard HSS — allowing it to maintain a sharp edge longer under the heat generated during parting operations. Frequently Asked Questions Is this compatible with the PD 250/E quick-change tool post?Yes — this holder is specifically designed for the PD 250/E quick-change tool post system. It mounts and locks in the same way as other quick-change holders for the PD 250/E. Are replacement tools available?Yes — spare parting tools (No. 24554) are available separately when the included tool wears out. Can this cut slots as well as part stock?Yes — the narrow 3mm tool width is suited for both parting (cutting off finished workpieces) and cutting slots and grooves in the workpiece.
