⚡ At a Glance
- • Holding Precision: Reliable concentric clamping for small workpieces
- • Best for: Machinists and hobbyists using lathe engraving machines and small CNCs
- • Not ideal for: Large-diameter work or setups requiring integrated quick-change systems
Hardened tool steel construction with a through hole for machining long parts. Precision engineering suits lathe engraving applications.
Secure, repeatable clamping – with hardened tool steel construction
Hardened tool steel increases surface hardness and resists deformation under clamping loads, preserving concentricity through repeated cycles. Heat treatment of the block promotes wear resistance in high-demand machining.
Consistent, durable clamping helps maintain part accuracy over long runs and reduces the need for rework.
Machine long stock without re-chucking – thanks to through hole design
A through hole runs axially through the collet block so bar or shaft stock can pass straight through during operations. That layout removes the need to reposition long workpieces mid-process.
Fewer interruptions and faster throughput when turning or engraving long shafts or rods.
Quicker setups for CNC benches – with an upright, compact block form
An upright-capable block presents the collet in a repeatable orientation for rapid insertion and alignment, simplifying fixture changes on CNC machines. The compact footprint keeps the work area tidy.
Reduced setup time and clearer bench organisation suit small-batch production and prototype runs.
