BM07 Holder BMB07.A16.16

The BM07 holder BMB07.A16.16

is a steel shank designed to clamp BM07‑series internal boring, grooving and threading inserts for CNC and Swiss‑type lathes. It comes with a 16 mm diameter shank and a 07 mm insert seat, paired with M3‑10‑T8 screw and T8‑Q wrench. The rigid steel body delivers stable working performance for small‑hole cutting tools during machining.

Product Overview

The BMB07.A16.16 is a BM07‑series tool holder for securing BM07 internal cutting tools with a 07 mm insert seat. It enables turning centers and Swiss‑type lathes to run BM07 boring, grooving and threading units with accurate positioning and proper clamping force. This holder acts as the connecting interface between machine turret and small‑hole cutting head.

Structure and Material

This is standard BMB07.A××.×× steel‑type holder. It features 16 mm shank diameter DCONMS, 16 mm usable length LU and 97 mm total length LF. The insert seat DCONWS measures 07 mm, and clamping is completed by M3‑10‑T8 screw together with T8‑Q wrench as specified in catalog. Tungsten carbide version BMB07.E×× series is also available for higher rigidity requirements.

Coating and Performance As a tool holder, surface coating is not required. Its overall performance relies on shank rigidity and insert‑seat machining accuracy. The special positioning structure from catalog provides outstanding tool strength and rigidity, which is the core advantage of SC / BM small‑hole tool system. Users shall select matching cutting insert grades such as TA51 or TD51 separately.

Applicable Workpiece Materials

The holder itself does not directly participate in cutting. Machinable workpiece materials depend on the fitted BM07 inserts. It supports P, M, K, N material groups including steel, stainless steel, cast iron, aluminum and copper, subject to insert grade selection.

Machining Application

It is used for installing BM07 boring, grooving and threading heads to perform internal machining tasks on CNC lathes and Swiss‑type sliding‑head lathes. It follows BM‑series recommended cutting parameters: cutting speed 40‑80 m per minute for steel material, 40‑60 m per minute for stainless steel, feed rate shall be set according to actual machining operation.

Equipment Compatibility

Compatible with all BM07 internal tools of 07 mm insert seat, including R/LBM07.××× boring series, R/LBM07.G××× grooving series and BM07 threading tools. Suitable for standard CNC turning centers and Swiss‑type lathes that accept 16 mm round shank. It cannot be mixed with other insert series, please use matched BM07 cutting heads only.
