Schaftfräser – shank milling cutter body with internal coolant, 20 mm shank (Teknik Makina)

The Schaftfräser is a shank-mounted milling cutter body designed for use with APKT 1003 indexable inserts, engineered for workshop and light industrial milling where quick insert changes and coolant-fed cutting improve process stability.

• 20 mm shank diameter
• Internal coolant supply
• Compatible with APKT 1003 inserts
• Three cutting edges for stable cutting

Improved tool life and surface quality through internal coolant

The integrated internal coolant channel directs cutting fluid precisely to the cutting zone, reducing heat build-up and flushing chips away from the insert edge. This targeted cooling lowers thermal stress on the insert and cutting body, which results in longer insert life and more consistent surface finishes across batches. For shops aiming to reduce unplanned downtime, the coolant feed is a measurable enhancement: fewer thermal tool failures and a reduced need for early index changes translate into improved machine availability and predictable production output.

Rigid shank and secure clamping for accurate, vibration‑resistant cuts

A 20 mm shank combined with an overall length of 120 mm and a cutting length of 40 mm gives the tool a balanced stiffness-to-reach ratio. The three cutting edges contribute to smooth chip load distribution, reducing chatter and improving dimensional stability. Insert retention is secured with an M2.5x5.5 screw tightened with a Torx T8 key, ensuring consistent seating of APKT 1003 indexable inserts from manufacturers such as Korloy. The low mass (approx. 0.278 kg) further aids tool handling and changeover, making the cutter body practical for both short runs and repetitive production cycles.

Economical, workshop-friendly design for efficient insert milling

The indexable-insert concept keeps running costs low: worn edges are quickly rotated or replaced instead of replacing the whole cutter head, which yields immediate cost benefits for small and medium-sized workshops. The cutter body is intended for rapid insert changes and repeatable mounting, supporting lean workflows and reduced setup time. Supplied as a purpose-built tool body by Teknik Makina and identified as S166-1TM, it fits into existing tool holders for conventional milling machines and offers straightforward integration into standard machining processes. For complex material questions or process optimisation, technical assistance is available via Metav Werkzeuge to support selection and application.
