Teknik Makina Vollbohrer — drill body, ø28.5 mm, 84 mm cutting length

Teknik Makina Vollbohrer is a heavy‑duty drill body designed for indexable‑insert drilling in production environments, compatible with SPMG 0904 inserts and common insert manufacturers.

• ø28.5 mm cutting diameter
• 84 mm effective cutting length
• 25 mm shank for secure clamping
• Compatible with SPMG 0904 inserts

Precision and productivity for indexable drilling

The drill body delivers a balance of rigidity and serviceability that suits serial production. With a 28.5 mm nominal diameter and an 84 mm cutting length, the tool provides an extended engagement zone that reduces the number of passes required for medium‑depth holes. The 25 mm shank diameter gives a reliable clamping interface for standard toolholders, while the overall length of 168 mm maintains reach without compromising stability. These measured dimensions make the component straightforward to specify for CAM setups and tool lists.

Fast insert changes and proven compatibility

Designed to accept SPMG 0904 indexable inserts, the drill body enables rapid insert replacement and economical reconditioning of the cutting edge. Compatibility with insert manufacturers Taegutec and YG‑1 broadens sourcing options and supports common workshop inventories. The replaceable‑insert approach reduces tool change time compared with solid carbide options and lowers per‑hole tooling costs, while the moderate mass of 0.572 kg contributes to predictable dynamic behaviour during high‑throughput cycles.

Operational benefits and workshop integration

The drill body suits machine shops that prioritise uptime and predictable results. Its geometry and shank proportions facilitate secure mounting in standard holders, helping to maintain concentricity over long runs. Where tool life and maintainability are critical, the indexable design separates wear‑sensitive cutting edges from the main tool body, simplifying maintenance and extending service intervals. For procurement and production planning, the straightforward technical profile supports BOM entries and rapid replacement sourcing.
