Parting clamp holder K831-1TM — 12.5 mm diameter, 125 mm length (Teknik Makina)

A Parting clamp holder K831-1TM designed for secure parting and grooving tasks on CNC lathes and turning centres, offering precise clamping for narrow-groove applications in workshop and production environments.

• High clamping stability with Torx T7 screw
• 12.5 mm diameter for narrow groove operations
• 125 mm overall length for deep setups
• Compatible with S10K ISO shank

Precision and compatibility for controlled parting

The K831-1TM is a compact parting clamp holder engineered for reliable, repeatable clamping in turning operations. With a diameter of 12.5 mm and an overall length of 125 mm, the holder is tailored for installations where space is limited but process control is essential. The shaft Ø 10 mm ensures compatibility with standard tool posts and adaptors, while the ISO designation S10K indicates straightforward interchangeability with common boring-bar and holder systems. These attributes reduce set-up time and simplify inventory, delivering measurable gains in process efficiency.

Secure clamping and improved surface results

Clamping integrity is central to consistent results; this holder uses a Torx-driven fastening system ( Torx T7 ) with an M2.2x6 screw, delivering firm seat and reduced micro-movement during cutting. The combination of cutting height 25 mm and cutting head width 6.8 mm supports stable engagement of the cutting insert, while the max parting depth 2 mm defines safe operational limits for narrow-groove procedures. Reduced vibration from a stable clamping arrangement improves surface finish and prolongs insert life, translating into lower tooling costs and fewer reworks for production-critical batches.

Practical handling and workshop advantages

Weighing 0.75 kg, the holder is robust yet easy to handle during tool changes and set-up. The design keeps maintenance straightforward: standard tool keys (Torx T7) and a single screw fixation simplify insert seating and replacement. For workshops aiming to standardise tooling across multiple lathes, the S10K compatibility and compact form factor make the holder suitable for small-batch work, repair tasks and continuous production alike. The construction prioritises repeatability and ease of alignment so that cycle times remain predictable and tool performance stable across shifts.

FAQ

What machines are suitable for this holder?
The K831-1TM parting clamp holder is suitable for CNC lathes and turning centres where a 12.5 mm diameter tool and shaft Ø 10 mm interface are compatible; use with standard tool posts and adaptors that accept S10K-style shanks.

Which insert sizes and cutting depths are appropriate?
The holder supports a cutting head width of 6.8 mm and a cutting height of 25 mm, with a recommended max parting depth of 2 mm; these limits help ensure secure clamping and reliable cutting performance.

How is the clamping secured?
Clamping is achieved with a Torx-driven fixation using a Torx T7 key and an M2.2x6 screw, providing firm seating to minimise micro-movement and vibration during parting operations.

Is the holder suitable for high-speed parting?
The design focuses on stability and repeatability; compatibility with S10K shank standards allows integration into typical production setups where speed is governed by the selected insert and machine capability.
