Key Features

  • HT300 Cast Iron Construction: High-grade grey cast iron provides superior vibration damping and rigidity for smoother cuts and better surface finishes.
  • Hardened Scroll & Gears: AISI 5140 alloy steel scroll (HRC 43-48) and bevel gears (HRC 45-50) for smooth, precise operation and long service life.
  • Hardened Jaws (HRC 52-58): AISI 1045 carbon steel jaws through-hardened for maximum grip strength and wear resistance.
  • Guaranteed Precision: Every chuck tested with 4 different diameter test bars. Repeatability ≤0.05mm (0.002").
  • Plain Back Mount: 3× M8 mounting holes. Note: Requires a separate adapter plate compatible with your lathe's spindle nose.
  • Includes External & Internal Jaws: Comes with both external jaws (3–72mm) and internal jaws.
  • T-Key Included: Robust T-handle key. Remove before operation.

Error-Free Jaw Installation

Numbered jaws (1, 2, 3) match the chuck body slots for quick, accurate installation. Prevents misalignment and ensures optimal concentricity.

Versatile Applications

  • Lathe: General turning, facing, drilling, boring
  • Milling Machine: Workpiece holding for milling
  • Drilling Machine: Precision drilling setups
  • CNC Machine: Light CNC turning and production

Compatibility Guide

Suitable for small benchtop lathes.
Sizing Rule: Lathe swing diameter > Chuck diameter (100mm). Allow clearance for jaw extension. A swing of ≥130mm is ideal.

Maintenance

Regularly clean the scroll mechanism and apply Molybdenum Disulfide (MoS2) grease to the scroll teeth and bevel gears. Store in a dry environment.
