  • Returns quill automatically after drilling via 1540mm expand length
  • Resists corrosion with chemical blackening oxide film finish
  • Fits multiple drill presses using hook mounting on both ends
  • Durable 60Si2Mn spring steel handles repeated compression cycles
  • Two springs included for immediate replacement or spare part

Drill Press Quill Return Spring

This two-piece set of quill return springs fits drill presses that use a 56mm outer diameter coil with hook mounts on both ends. The springs are made from 60Si2Mn spring steel with a chemical blackening finish that forms an oxide film to resist rust. Each spring measures 1540mm expanded length and uses 10mm wide, 1mm thick material. They restore automatic quill retraction after drilling.

56mm Outer Diameter Hook Mount

The single specification that decides fit is the 56mm outer diameter combined with inner and outer hook mounting points. Measure the existing spring housing and mounting style before ordering; a different diameter or mounting type will not work. The 1540mm expanded length must also match the quill travel of the press.

Two Springs for Spare or Dual Machines

The package includes two identical springs so you can replace a broken unit and keep a spare on hand, or service two compatible drill presses at once. Installation requires threading the fixed wire through the spring and allowing it to slide out; the wire must not be loosened during fitting. No other hardware is included.

Questions about this item

What does the 1540 mm expanded length mean once the spring is installed on my drill press?

The 1540 mm expanded length is the total stretch of the coil when the quill is fully lowered; it determines how far the spindle can travel before the spring reaches its limit.

What do the hook-type inner and outer mounts cap in practice?

Both ends use a hook that catches on the existing anchor points inside the head casting and on the quill shaft, so the spring cannot be used on presses that require a loop or tang fitting.

What physical space does the 56 mm outer diameter and 10 mm material width need to fit?

The coil needs a 56 mm diameter bore or housing clearance, and the 10 mm wide strip requires at least that much axial room between the mounting hooks.
