Type B1 Tool Holder

Processing Applications

1. Rough, semi-finish and finish OD turning operations: machining outer diameters, steps and chamfers of shaft workpieces, as well as cutting outer edges of end faces.

2. High-rigidity machining with short overhang: Form B1 features a compact structure with minimal tool projection, offering superior vibration resistance compared to extended Form B3 holders.

3. Conventional right-hand turning for forward-feed OD machining processes.

4. Most B1 holders are equipped with central coolant channels, delivering high-pressure cutting fluid directly to cutting edges, ideal for machining stainless steel, alloys and mass production.

5. Compatible with standard square-shank carbide or coated turning tool bars (square sizes: 12/16/20/25/32mm).

Core Advantages

1.High rigidity with short overhang

The compact body minimizes tool extension, effectively suppressing chatter during heavy and interrupted cutting, and improving surface finish and dimensional consistency of workpieces.

2.Standard serrated VDI shank

Serrated taper shank locks tightly onto the turret, ensuring high repeat positioning accuracy and tiny concentric runout after tool changes.

3.Multi-bolt clamping for square tool bars

Adopts 3 top clamping bolts plus side jacking structure to firmly lock tool bars without shifting, even under heavy rough turning loads.

4.Built-in coolant passages

Internal high-pressure cooling enables efficient heat dissipation and chip evacuation, extending insert service life and suiting automated mass production.

5.Strong universal compatibility

Standardized dimensions allow interchangeability across VDI turrets of various brands. Made of 42CrMo steel quenched to HRC58 overall, precision ground on working surfaces for outstanding wear resistance.
