Composite Straight Flute Drill Bit with High Fracture Resistance and Internal Coolant

In the field of efficient drilling and complex hole processing , tool with precision and efficiency is the "accelerator" on the production line.

The internally cooled with straight groove drill (double straight hole) D12.5 × 24.5 developed by AMG designed to meet high-precision, high-efficiency, and many machining needs. It integrates multi-stage drilling, dual channel cooling, high-quality materials, and scientific chip removal structure, and is widely used in the machining of workpieces.

application

AMG internal cooling composite straight groove drill is widely used for machining composite holes such as stepped holes, through holes,  in automotive engine cylinder blocks, mold plates, and machined structural components.

Product Performance

Cutting diameter accuracy: ± 0.01mm

The roughness of the hole wall can reach Ra0.8~1.6 (depending on the material and cooling conditions)

Excellent anti chipping performance, suitable for intermittent cutting and deep hole machining

Long life, high machining stability per blade, and excellent tool balance

Working principle

Adopting two straight hole internal cooling structure, the coolant flows directly through the internal channel of the drill body to the cutting edge during cutting, effectively cooling the tool and carrying out chips, avoiding chip stock and thermal deformation. Cooperate with straight groove geometric design to ensure smooth drilling process, good guidance, and improve the verticality and smoothness of the hole position.
