Thread milling cutters

Catalog thread mills cover metric coarse threads M0.8–M33, fine threads to M48 and, by pitch, sizes to M80; other sizes are made to order. Single-form, 3-tooth and multi-row geometries, plus 3xD / 4xD and long-reach versions, UN, pipe, trapezoidal, ACME and PG threads. Pipe, trapezoidal, ACME and 3-in-1 thread mills can all be ordered. One cutter covers a range of thread sizes at the same pitch, and tool breakage may leave the part recoverable, depending on the damage and application.

Full size tables for every series are in catalog chapter 05, Thread mills (PDF). Pre-hole tables and starting cutting data are in chapter 07, Technical data (PDF). No prices.

Dimensions are in millimetres: d1 cutting diameter, d2 neck, L1 reach, D shank, L overall length. Pitch is in mm for metric threads and in TPI for UN, pipe, ACME and PG threads.

Packaging

Every tool is packed on its own: a tip cap protects the cutting edge, and each shank tool sits in its own reusable tube, sized to the shank and length and labelled for your order.
Micro tools (drills and end mills below about Φ3) go in micro tubes that hold the tool without touching the edge.
Inserts and crown drill tips are packed in slotted insert boxes, 10 per box for standard inserts.
Tubes are grouped in 5- or 10-piece boxes, then packed in export cartons sized to the order; reinforced or palletised packing for sea freight on request.
