Benefit from a compact, rigid toolholder that combines internal coolant supply and precise indexable-insert compatibility to raise machining stability and shorten tool-change time. Order the A12K SDQCR directly via Metav Werkzeuge or consult the technical advisers for application support.

A12K SDQCR – SDQC right‑hand indexable‑insert holder with internal coolant (Teknik Makina)

The A12K SDQCR is a right‑hand indexable‑insert holder designed for external turning and light boring applications, providing through‑coolant capability and compact 12 mm shank dimensions for space‑restricted toolposts.

• Internal coolant channel for reliable chip evacuation
• Suitable for DC-- 0702 indexable inserts
• 12 mm shank for compact toolholders
• Right‑hand orientation with 107.5° cutting angle

Improved process stability through internal coolant and rigid shank

The holder’s internal coolant route delivers cutting fluid directly to the cutting edge, aiding chip control and reducing thermal load at the insert. Combined with a 12 mm shank and a short 125 mm overall length, the component reduces overhang and vibration, which in turn supports consistent surface finish and longer insert life. For workshops that run series production on small lathes or multi‑turning centres, this arrangement lowers scrap rates and enhances machine uptime by stabilising the cutting process.

Broad compatibility with DC-- series inserts for faster tool changes

Designed specifically for the DC-- 0702 insert family, the toolholder accepts standard indexable plates and uses a proven clamping geometry to secure the insert reliably. The 107.5° cutting angle and right‑hand orientation suit conventional external turning feeds; the indexable system allows quick rotation of the insert to a fresh edge without reclamping the holder, improving labour efficiency and reducing spindle idle time. This compatibility simplifies inventory: one holder supports a commonly stocked insert format, easing workshop logistics.

Practical benefits for workshop organisation and choice

Weighing just 0.11 kg and featuring a nominal 16 mm diameter at the cutting zone, the holder is easy to store and handle while remaining compatible with compact toolposts. The ISO designation A12K SDQCR indicates the shank geometry and clamping style, which assists buyers in matching holders to existing toolblocks. Where process parameters are critical, Metav’s application guidance can help select the correct insert grade and cutting data for different materials, ensuring the holder is deployed to best effect.

FAQ

Is this holder compatible with DC-- 0702 inserts?
Yes. The A12K SDQCR toolholder is manufactured for use with DC-- 0702 indexable inserts and secures the plates with standard clamping geometry.

Does the holder provide through‑coolant delivery?
Yes. Internal coolant channels are integrated, supplying fluid directly to the cutting edge to aid chip control and cooling.

What shank and overall dimensions should be expected?
The holder has a 12 mm shank, a 16 mm cutting‑zone diameter and a 125 mm overall length (KA142TM), suitable for compact toolposts.

Is the toolholder suitable for left‑hand turning?
No. The A12K SDQCR is a right‑hand orientation holder; left‑hand operations require a left‑hand counterpart.

Which manufacturer produces this item and who is the responsible distributor?
Teknik Cutting Tools is the manufacturer of this holder; sales and distribution are managed via Metav Werkzeuge for the European market.
