ICF Series 15xD Coolant Through Carbide Drill Bits 2.4-20mm Internal Coolant Gun Drill Replacement

The ICF Series 15xD coolant through solid carbide drill is engineered for extreme deep hole machining, delivering true gun drill replacement performance in modern CNC machining centers.

With a drilling depth of 15xD, ultra-wide parabolic flutes, and high-pressure dual internal coolant channels, coolant is delivered directly to the cutting edge throughout the entire drilling cycle. This effectively controls heat, chip evacuation, and straightness — even in stainless steel, mold steel, and hard steel up to 55 HRC.

The reinforced shank geometry ensures hole straightness < 0.06mm at full depth. Combined with imported sub-micron carbide substrate and advanced AlCrN coating, the ICF 15xD achieves comparable tool life to traditional gun drills at approximately one-third of the cost.

This makes the ICF 15xD series an ideal solution for hydraulic valve blocks, deep mold cavities, aerospace long holes, and other high-value components where gun drilling was previously required.
