Product Overview

These metal and plastic laminate 'stones' have industrial diamonds bonded to them. They are well suited for removing rock damage from, as well as, sharpening and polishing ski and snowboard edges.

  • DMT diamond stones last a long time if kept clean (use a brass brush and an abrasive cleaner, like Bon Ami®, rinse with water)
  • Use with light pressure (a heavy hand can prematurely break diamonds loose from the stone). 
  • We also use them wet (dip 'em in a cup of water or use edge polishing solution) to help keep debris from clogging the diamonds.
  • 100mm (4 inches) long.
  • Also available in 70mm length
  • Sold each or as a set of four.
OPTIONS AVAILABLE:
 
SILVER
  • Extra-Extra Coarse  (120 grit) 
  • Best for repairing extreme rock damage on steel edges.
  • Also good for resurfacing natural stones (aluminum oxide, etc.).
BLACK 
  • Extra Coarse  (220 grit) 
  • Best for repairing rock damage on steel edges when they've been 'work-hardened' by impact and look glazed and/or ragged.
  • First stone for resharpening edges if you want to avoid filing.
  • Also good for re-sharpening carbide tips on ski skating poles
BLUE 
  • Coarse (325 grit)
  • Use the medium blue model  for deburring side edges after filing or beveling.
RED
  • Fine (600 grit)
  • for finer deburring and edge polishing.
GREEN
  • Extra fine  (1200 grit)
  • The extra-fine green stone for even smoother finishes.
SET OF FOUR
  • Includes all four stones and a nylon pouch.

    The DMT Diamond

    Posted by Mike King on Mar 03, 2024

    The DMT diamond stone is longer that other brands of DIA Stones which works much better and doesn’t tend to rock and roll on while on top of the SVT 92 degree file guide, messing up the edge just filed.

    Diamond Stone

    I use this after I use a file on my base or edges or by itself if there isn't a lot of need to remove material. Pair it with a Beast and your set.

    DMT 4 inch diamond stone set of 4

    I purchased these to use with the SVST side and base edge bevel tools. I have the 2.75 in. version for a multi tool but upgraded to a better set of tools. Glad I did these work faster and provide a more consistent result. These are solid stones with the right size and range of grits to really get to the right edge on my skis. They create an extremely sharp smooth edge well worth the price !

    Good stones

    Posted by Unknown on Jan 04, 2018

    I have four different grit sizes of these stones that I use in combination to tune my ski edges. I prefer these over a file because they do a good job without taking off too much of the edge. They are easy to use and clean.

    quick work on hardened edges

    Posted by Spade Hackle on Mar 12, 2014

    One or two passes with this diamond stone removes rock burs and the scored/hardened edge allowing your sharpener to get the job done in a pass or 2.

    Less metal better edge

    Posted by Jim O'Neil on Mar 12, 2014

    These are a great way to manage your edges. Take metal off once a season with a file to define base and edge bevels, then sharpen with these diamond stones. Go from Extra coarse to fine and it brings the edge right back. Awesome tool.

    Basic diamond, but ez fitment in many edging tools

    Posted by Unknown on Feb 15, 2014

    I think the Moonflex Diamond stones are superior, however this diamond stone is a little narrower and fits in many edge and base tools, so it is a little more versatile and definitely economical.

    Good Diamond Stones

    Posted by Joe on Feb 05, 2014

    Good basic (value) diamond stone. It works fairly well though in the future I will probably buy a stone that has more diamond surface to reduce the number of passes needed on the ski edges. Works well with my edge tool.
