Shank milling cutter for BOMT 1304 indexable inserts — 20 mm shank, internal coolant (Teknik Makina)

Shank milling cutter designed as an indexable-insert milling solution for precise CNC face and slot operations, compatible with BOMT 1304 inserts and engineered for secure clamping and coolant-fed performance.

• 20 mm shank diameter
• Internal coolant supply
• Compatible with BOMT 1304 inserts
• Includes T10 Torx screw M3.5x8.5

Increased rigidity for repeatable machining and reduced runout

The tool's 20 mm shank combined with a 150 mm overall length delivers a balance between reach and rigidity that supports repeatable machining cycles. A stiffer shank reduces vibration and runout, which in turn helps to maintain insert geometry and surface integrity on the workpiece. For production environments where consistent tolerance adherence matters, the robust shank dimension translates directly into fewer scrap parts and more predictable tool life. The compact mass of 0.356 kg keeps toolholder loads moderate while supporting reliable spindle dynamics.

Fast insert changes and secure clamping to keep downtime low

Designed for BOMT 1304 inserts and accepted by Ingersoll systems, the cutter uses a proven indexable-insert concept that separates cutting edge expenditure from the tool body. The two cutting edges and the 40 mm cutting length enable effective material engagement with reduced cutting forces per tooth. Clamping is secured with a T10 Torx drive and M3.5x8.5 screw, providing a straightforward and repeatable tightening procedure; spare screws and the specified Torx key simplify maintenance. This configuration shortens tool-change intervals and limits operator time spent at the machine, improving overall equipment effectiveness.

Coolant-fed cutting for extended insert life and improved surface finish

The integrated internal coolant channel supplies cutting fluid directly to the insert seat and cutting edge, which assists chip evacuation and reduces thermal loading on the carbide grade. Direct cooling helps to prevent premature insert wear and to maintain consistent cutting geometry over longer cycles, supporting better surface finishes and tighter tolerances. For mixed-shop environments where switching between roughing and finishing passes is common, the coolant-fed design offers process reliability and reduces the frequency of unscheduled maintenance.

Practical compatibility and workshop integration

This milling solution arrives as a ready-to-fit shank tool that aligns with standard indexable-insert workflows. The tool body integrates with common tooling systems and is suitable for use in serial production and job-shop contexts where fast insert replacement and reliable clamping matter. Documentation on insert orientation and screw torque should be followed to ensure optimal performance. For technical clarifications on insert grades, clamping torque or specific machining strategies, advisory support is available.
