Key features

Equipped with double internal coolant channels. Cutting fluid flows directly to drill point to dissipate heat efficiently and greatly reduce thermal wear of the tip.

Coolant continuously flushes flutes to realize smooth chip evacuation in deep hole drilling, prevent chip jamming and avoid scratching the inner hole surface.

Premium solid carbide blank provides high rigidity, minimizes vibration during deep hole drilling with large L/D ratio and reduces drill breakage risk.

Fully precision ground drill point ensures accurate centering and low runout, guaranteeing hole dimensional accuracy and straightness for deep holes.

High-performance wear-resistant coating is optional with great heat and oxidation resistance, suitable for carbon steel, alloy steel, stainless steel, mold steel and other materials.

Optimized spiral helix angle reduces cutting resistance, allows higher feed rate and improves production efficiency of deep hole machining.

Standard straight shank offers stable clamping, compatible with CNC machining centers, CNC lathes and deep hole drilling machines with internal coolant supply.

Multiple length-to-diameter ratios in stock, covering general drilling and deep hole machining working conditions.

Double internal coolant holes deliver fluid directly to tip for rapid cooling and reduced thermal wear.

Direct cutting tool manufacturer . Custom OD, overall length and L/D ratio are available, OEM orders are accepted.
