Vent drill bit selection guide

Why vent holes matter

Vent holes let trapped air escape from the mold during curing, preventing air pockets and defects on the tire. Clean, well-drilled vents also reduce build-up and wear on the mold and make release easier.

Temis vent drill bits are heat-treated with a special process that makes them specifically suitable for drilling and cleaning vent holes in industrial molds. They work both for cleaning existing vent holes and for drilling new ones.

This guide helps you choose the right vent drill bit for the maintenance of your molds.

Materials · Geometries

Three materials, three geometries

HSS/Co and M2 drill bits are a must for small diameters: exactly what vent holes in tire molds require. Drilling in different mold materials requires a different helix (flute) geometry.

HSS/Co

High-speed steel with 9% cobalt · our standard
  • High elasticity and hardness
  • More flexibility and abrasion resistance than standard HSS

HSS

High-speed steel
  • Best choice for tight or precision tolerances
  • Especially when drilling relatively deep holes

M2

Molybdenum high-speed steel
  • A milder grade some customers prefer
  • Good toughness and wear resistance
StandardThe everyday geometry for drilling and cleaning vent holes
QuickSteeper helix, faster chip removal, quick cleaning cycles
ParabolicAluminium and deep holes: better chip evacuation and finish
ChucksAdaptors that hold small bits firmly on any drilling machine
