Upgrade your milling operations with precision-engineered milling chucks. Our milling chucks are versatile, high-accuracy toolholders with very high gripping power and very low runout. They are great for heavy milling applications, and for holding larger diameter tool shanks. The solid one-piece construction and symmetrical design of the toolholder provide high accuracy and good balance characteristics, ensuring optimal performance in metalworking and manufacturing.
MILLING CHUCKS AND COLLETS OVERVIEW
Milling chucks are versatile, high-accuracy toolholders with very high gripping power and very low runout. They are great for heavy milling applications, and for holding larger diameter tool shanks. The solid one-piece construction and symmetrical design of the toolholder provide high accuracy and good balance characteristics.
Milling chucks are designed to hold a single size tool shank, and then precision straight-shank reducing collets are used to hold smaller diameter tools. The straight collet design provides even clamping along the entire length of the shank, eliminating axial movement of the tool, increasing rigidity, and minimizing runout. This results in high gripping force for heavy milling.
Simple twist-lock operation and high retention force make these milling chucks ideal for general purpose operations.
NOTE: Never tighten a milling chuck without a tool in the toolholder, or clamp on a tool that is too small for the holder or collet sleeve.
Features:
- Low runout
- Simple twist-lock operation
- High grip strength
- Excellent tool retention
Milling Chuck Instructions
Assembly
- Clean the inside of the milling chuck, collet, and tool.
- Insert the appropriate size collet and tool into the milling chuck.
- Tighten using the spanner wrench until the cap contacts the body of the chuck. Full-face contact must occur between the cap and the chuck body.
CAUTION
- Never tighten the milling chuck cap without a tool inside of it — permanent damage will occur.
- Only install smooth shank tooling into the milling chuck. Weldon flats and other side-lock style tooling will not be held with as much force and can cause the bore of the milling chuck to permanently deform.
Tool Removal
- Loosen the cap with the spanner wrench until the tool can be removed.
- Remove the tool.
- Loosen the cap until it’s out and continue to loosen it an additional 1 to 2 turns. This will re-align the bearings and ensure full and accurate clamping the next time the milling chuck is used.
