DORIAN

DORIAN indexable turning toolholders are available in standard shank sizes such as 16 mm, 20 mm, and 24 mm, as indicated by model numbers like MDJNL165D (16 mm shank), MVLNL204D (20 mm shank), and MTGNL164D (16 mm shank). The shank size is typically encoded in the model number: the first two digits after the letter code represent the shank height in millimeters (e.g., '16' = 16 mm). These toolholders are designed to fit standard tool post holders and turret stations on manual and CNC lathes.

DORIAN quick-change tool posts, such as the SDN50DA model for lathe swings from 17 in to 32 in, are designed to fit lathes with a compatible mounting configuration. The tool post uses a dovetail clamping system that is standard across many lathe brands, but compatibility depends on the lathe's compound slide dimensions and bolt pattern. For specific lathe models, verify the tool post's base dimensions and the center height relative to the spindle. DORIAN tool posts are commonly used on manual lathes from brands like South Bend, LeBlond, and Clausing, but no universal compatibility is guaranteed.

DORIAN indexable toolholders are designed to accept specific insert shapes based on the toolholder model. For example, the MDJNL165D uses an 80° diamond insert (DNMG style), the MVLNL204D uses a 55° diamond insert (VNMG style), and the MCLNR246E uses a 80° rhombic insert (CNMG style). The insert seat is precision-ground to ensure repeatable indexing. Always match the toolholder's insert seat code (e.g., 'D' for 80° diamond, 'V' for 55° diamond) with the corresponding insert shape to avoid clamping issues.

DORIAN diamond turning inserts, such as the CCGT-21.51-NFU (CCGT-060204-NFU), are typically made from polycrystalline diamond (PCD) or cubic boron nitride (CBN). PCD inserts are suited for non-ferrous materials like aluminum, brass, and plastics, while CBN inserts are used for hardened steels (45-65 HRC). The specific grade (DNX10UT in the MPN) indicates a CBN grade for hard turning. Verify the insert grade with DORIAN's technical data to confirm suitability for your workpiece material and hardness.

DORIAN finger clamp screws, such as MPN 73310190901, are specific to the toolholder model and clamping mechanism. The screw length, thread pitch, and head style must match the toolholder's clamp design. For example, the finger clamp screw for a MDJNL toolholder may differ from that of a MCLNR toolholder. Refer to the toolholder's parts diagram or contact 3G Electric with the toolholder model number to ensure the correct replacement screw is ordered.

3G Electric maintains an inventory of over 969 DORIAN SKUs, including common toolholder models like MDJNL165D and MCLNR246E. For in-stock items, lead time is typically 1-3 business days for order processing plus shipping time based on destination. For less common models or high-volume orders, lead time may extend to 2-4 weeks depending on DORIAN's production schedule. Contact 3G Electric for current stock status and estimated delivery dates.
