Product information

Description

GRAPHITE key-operated drill chuck model 56H631 is a replacement and upgrade component for hand drills and drill presses with a 3/8"x24 threaded spindle. The chuck accepts round and slightly tapered shanks up to 10.0 mm in diameter and uses a keyed tightening mechanism to provide secure mechanical clamping of drill bits. It is suitable for common workshop operations in metalworking, woodworking and plastics where a reliable, repeatable grip on the tool is required.

Advantages

The keyed design ensures high clamping torque and positive retention of cutting tools, reducing slippage during heavy drilling. Threaded 3/8"x24 mounting allows straightforward installation on compatible spindles without additional adapters. The 10.0 mm capacity covers a wide range of standard drill bit sizes used in domestic and light industrial applications, while the robust construction supports frequent use and simple maintenance.

Suitable for

  • Replacing worn or damaged chucks on hand drills with 3/8"x24 thread
  • Drilling in metal, wood and plastic using round or slightly tapered shank bits up to 10.0 mm
  • Home workshops, maintenance tasks and light production work
  • Drill presses and bench drills that accept a 3/8"x24 threaded chuck

Key specifications

  • Mount type: external threaded mount, 3/8"x24
  • Actuation: keyed tightening mechanism (requires key for clamping and releasing)
  • Maximum capacity: 10.0 mm drill shank diameter
  • Compatible shank types: round and slightly tapered shanks
  • Material and finish: steel construction suitable for workshop use (factory finish)

How to use

Ensure the drill or press spindle is powered off and secured. Thread the chuck onto the 3/8"x24 spindle and tighten by hand until seated, then secure fully by rotating the spindle or using the chuck key as required by the tool. Insert the drill bit into the jaws to the required depth, engage the chuck key in the geared socket and tighten incrementally at three positions around the chuck to ensure even clamping. After use, loosen the chuck with the key to remove the bit and clean the jaws of debris and swarf to maintain reliable operation.

Usage recommendations

Use the correct size and type of drill bit for the material and apply steady feed pressure to reduce risk of slippage. Periodically apply a light machine oil to the threads and jaws and remove chips from the jaws after each session to extend service life. Verify compatibility of the 3/8"x24 thread with your tool before installation.
