Invest in quality and buy for life!

Take your knife making to the next level with the 84 Engineering precision disc grinder. Disc grinders significantly reduce the hand sanding required to achieve a flat, high-grit finish on your blade bevels. Discs are also great for grinding billets flat or achieving accurate angles and flat faces on your ‘Wa’ style and other angular knife handles. Mount it vertically or horizontally to suit your needs!

PRECISION CNC MACHINED DISC - Flat or Bevelled Discs

Our 225mm diameter discs are precision CNC machined from billet 6061 Aluminum, ensuring a perfectly uniform work face. Avaiable "Flat" or "Bevelled" where the bevelled discs can be used for longer handles or blade grinding and finishing as they allow the work piece to pass over the centre of the disc without contacting the other side. The Aluminum is lightweight and provides exceptional heat dissipation and rigidity. A 10ᵒ relief on the disc edge makes sanding into tight areas and grinding crisp corners a breeze. The disc is sized so that standard 230x280mm sandpaper / abrasive sheets such as Rhynowet can be used. We recommend using 3M feathering adhesive or kraft spray adhesive to attach sheet to disc, then trimming the excess.

VARIABLE SPEED DRIVE ASSEMBLY - UK or Euro plug

The Variable Frequency Drive (VFD) will plug into any standard 230V 12A power socket and converts power to a 3-phase signal, driving the industrial 0.75kw (1.0HP) 4-pole motor (more torque than 2 Pole motors). The included VFD is tuned specifically for disc grinding and provides maximum torque throughout the programmed safe speed range. The ability to run the disc at low speeds means minimal heat build-up during high-grit finishing and shaping, and the 1440rpm on tap is useful for rapid stock removal and sanding of timber and synthetic handle materials.

The VFD is IP66 rated meaning it is grinding dust and weatherproof to defend against these big killers of drives.

MOUNTING FRAME and FULLY ADJUSTABLE REST

The 280x120 powder-coated work rest is both angle and height adjustable. The premium indexing handles lock the rest securely at any angle ensuring your grinds will always be accurate and repeatable. Depending on the application, the ability to adjust the height of the rest makes for safer grinding and better abrasive utilisation.

ABRASIVES

Your favourite abrasive belt materials can be supplied in sheet form for you to use on the Disc Grinder or abrasive sheets such as Rhynowet can be used.
