These coolant drills combine solid carbide substrates, engineered internal channels, and precise geometries to deliver reliable chip evacuation and stable hole quality in CNC machining. Standard 3xD, 5xD, 8xD, and extended 10–12xD options are available, with non‑standard designs built from drawings or samples. Manufactured in our Changzhou, Jiangsu plant on TTB, WALTER, DECKEL, and ANCA grinding centers, each tool achieves sub‑micron accuracy, mirror‑polished flutes, and repeatable performance across batches.
Optimized helical or straight internal channels, high rake, and polished flutes move chips quickly and support long tool life. Reinforced margins improve hole stability and reduce deflection.
Tight tolerances, runout, and geometry are verified on ZOLLER, PARLEC, and PG1000/MRPG1000 systems. ISO9001 and SGS‑backed processes help ensure consistent quality for automated cells and multi‑station machining.
We match carbide grades and coatings to each material group, balancing wear resistance and heat control. Share workpiece material, process, machine type, and clamping, and we fine‑tune geometry and channel design for difficult‑to‑machine jobs.
For stainless, duplex, Inconel, and titanium, micro‑grain carbide with AlTiN or TiSiN and 135–140° points reduces work hardening and burrs. High‑pressure coolant (50–80 bar) and polished flutes clear stringy chips in deep holes.
Wear‑resistant grades with TiAlN/TiSiN and double margins stabilize the cut at higher feed rates. Controlled edge prep resists micro‑chipping, and internal coolant limits thermal shock in interrupted or cross‑holes.
Polished flutes, high rake, and DLC or uncoated options minimize built‑up edge in aluminum, copper, and brass. Larger helical channels evacuate long chips and protect thin‑walled features.
Diameters from 0.8–20 mm, lengths 3xD to 12xD, and point angles from 130–140° cover most needs. The catalog includes 2‑ and 3‑flute layouts with helix angles tuned by material. Tools are produced to d1 h6 or better with DIN 6535 HA/HE/HB shanks. Recommended coolant pressure is 20–70 bar for general use and up to 80 bar for deep holes.
When standard tools don’t fit, we design coolant‑fed drills for specific materials, machines, and clamping. Options include step and pilot drills, spot or chamfer integration, form features, special margins, and tailored channel layouts to balance rigidity and evacuation in complex setups.
Channel diameter, helix, and outlet positions are modeled to maintain flow and stiffness for 3xD–12xD tools. Reliefs and margins are set to control heat and hole straightness in cross‑holes or angled entries.
Steels and high‑temp alloys pair well with AlTiN or TiSiN. Aluminum often benefits from DLC or uncoated tools. Micro‑polished flutes and controlled edge prep reduce cutting forces and extend tool life.
Integrated pilots or stepped profiles cut tool changes and improve entry alignment. They suit stacked plates and multi‑material parts where evacuation and alignment matter.
These tools run on vertical and horizontal machining centers and live‑tool lathes. Balanced geometries help minimize burrs and deflection on thin walls or angled surfaces. High‑pressure coolant supports reliable chip clearance in deep features.
Every tool is preset and inspected on ZOLLER, PARLEC, and PG1000/MRPG1000 to validate geometry, runout, and channel integrity. With TTB, WALTER, DECKEL, and ANCA grinding platforms, we deliver consistent batches backed by ISO9001 and SGS.
Use high‑precision collet chucks to reduce runout and enhance hole accuracy. Related CNC accessories and inserts support complete workflows and improve process reliability.
