Tungsten Carbide Rods with Coolant Holes — Straight & Helical
Tungsten carbide rods with one or two straight or helical coolant holes for drills and through-coolant cutting tools.
Through-coolant drills and reamers start from rods with coolant channels formed during pressing. The helix angle, hole diameter and hole position must match your tool design.
Typical applications
- Through-coolant drills and step drills
- Reamers and deep-hole tools
What we supply
- One or two straight coolant holes
- Helical holes at the helix angle you specify
- Ground or unground
Choosing the grade
Same grade logic as solid rods; tell us the tool type and workpiece material.
Grade data (binder content, grain size, hardness, density, transverse rupture strength) is confirmed in writing for the grade we propose. How we choose grades →
