Parting clamp holder K831TM — 12.5 mm, compact 125 mm length (Teknik Makina)

A robust parting clamp holder K831TM engineered for precise grooving and cut‑off tasks in CNC turning, featuring a standard 10 mm shank and a short overall length for restricted toolpost spaces.

• 12.5 mm cutting diameter compatibility
• 125 mm overall length for compact setups
• 10 mm shank for standard toolholders
• Max parting depth 2 mm with T7 Torx screw

Consistent, shop‑floor precision for tight spaces

Designed for repeated, dependable parting and grooving cycles, this toolholder delivers consistent results where accessibility is limited. The short 125 mm overall length reduces overhang and helps maintain rigidity, which translates into improved surface finish and reduced tool chatter. The compact design pairs with a 10 mm shank, permitting secure clamping in commonly used toolposts and quick change systems; this ensures minimal set‑up time and steady process control for batch and single‑piece production alike.

Efficient material removal with controlled depth and width

With a maximum parting depth of 2 mm and a 6.8 mm cutting head width, the holder is tailored for fine, accurate cut‑off operations rather than heavy roughing; this reduces spindle load and extends insert life in finish or semi‑finish passes. The 25 mm cutting height allows correct insert positioning and stable engagement, so the toolholder supports predictable chip formation and easier downstream inspection. For workshops seeking reliable, low‑vibration performance, the geometry focuses on repeatability and economical tool consumption.

Practical fastening and straightforward maintenance

The clamping system uses a Torx T7 interface and an M2.2x6 fastening screw to secure the insert clamp, providing a compact, low‑profile connection that is simple to access with standard Torx tools. The arrangement simplifies insert changes and maintenance, reducing downtime during shift changes or tool swaps. At a weight of approximately 0.74 kg, the holder balances robustness and manoeuvrability, enabling technicians to handle and position the assembly easily without excessive strain.

FAQ

What is the shank size and how does it fit standard toolposts?
The holder uses a 10 mm shank diameter, and the parting clamp holder K831TM is designed to clamp securely in standard 10 mm toolposts and quick‑change adaptors.

What maximum parting depth can be achieved with this toolholder?
The maximum recommended parting depth is 2 mm, enabling the K831TM to perform precise cut‑off and finish grooving operations with stable engagement.

Which fasteners are used to secure the clamp and insert?
Fastening is by a Torx T7 interface and an M2.2x6 screw; the parting clamp holder K831TM uses this compact fastening to allow quick, accessible insert changes.

What overall length should be expected and why does it matter?
The overall length is 125 mm; this compact dimension reduces overhang, improving rigidity and repeatability for the K831TM in constrained turret or toolpost arrangements.

Is the toolholder suitable for heavy roughing cuts?
The geometry and 6.8 mm cutting head width are optimised for precise parting and finishing operations rather than heavy stock removal; the K831TM is best used for controlled, repeatable cuts rather than aggressive roughing.
