GRS 023-123 Blue Medium Diamond Wheel for Gravers
The GRS 023-123 Blue Medium Diamond Wheel is designed for refined shaping of carbide and HSS gravers. Its medium diamond abrasive provides controlled material removal after initial rough shaping, making it an excellent second-stage wheel for creating accurate graver geometry and preparing tools for final polishing.
The compact 25 × 2.5 mm diamond wheel features a 2.35 mm (3/32") shank and mounts easily in compatible micromotors and flex-shaft systems, including NSK EVO, Electer, and Foredom hanging motors. With a maximum operating speed of 5,000 RPM, it is designed for controlled, precise graver shaping.
Use the GRS Blue Medium Diamond Wheel after a coarse roughing wheel such as the GRS 023-122 Gray Roughing Diamond Wheel, then move to the GRS 023-120 Yellow Rubber-Bond Diamond Polishing Wheel for final polishing and finishing. GRS identifies these wheels as complementary options for shaping and polishing carbide and HSS gravers.

Refined Graver Shaping
The GRS 023-123 is particularly useful when you need more control than a coarse roughing wheel provides. The medium diamond surface allows engravers to refine the shape and geometry of a carbide or HSS graver before moving to a polishing wheel.
For the best results, use the wheels progressively:
GRS 023-122 Gray Roughing Diamond Wheel
For fast initial shaping and material removal.
GRS 023-123 Blue Medium Diamond Wheel
For refined shaping and establishing accurate graver geometry.
GRS 023-120 Yellow Rubber-Bond Diamond Polishing Wheel
For final polishing and achieving a smooth, finished graver surface.
GRS lists the three wheels as a complementary system for shaping and polishing carbide and HSS gravers.
Ideal For
The GRS Blue Medium Diamond Wheel is an excellent choice for:
- Professional hand engravers
- Jewelry engravers
- Knife engravers
- Firearms engravers
- Stone setters
- Metalsmiths
- Toolmakers
- Engraving students
- Anyone sharpening or reshaping carbide and HSS gravers
Frequently Asked Questions
What is the GRS 023-123 used for?
The GRS 023-123 Blue Medium Diamond Wheel is used for refined shaping of carbide and HSS gravers. It is intended to follow a coarser roughing wheel and prepare the graver for final polishing.
What size shank does the GRS 023-123 have?
The wheel has a 2.35 mm (3/32") shank.
What is the maximum RPM for the 023-123?
The maximum operating speed is 5,000 RPM.
Can I use this wheel with an NSK EVO?
Yes. GRS states that the Blue Medium Diamond Wheel easily mounts in micromotors such as the NSK EVO and Electer. It can also be used with compatible Foredom flex-shaft hanging motors.
Can the GRS 023-123 sharpen carbide gravers?
Yes. The 023-123 is specifically designed for refined shaping of carbide and HSS gravers.
What wheel should I use before the GRS 023-123?
For substantial material removal and initial shaping, use the GRS 023-122 Gray Roughing Diamond Wheel first. The 023-123 then provides the medium-stage refinement before final polishing.
What wheel should I use after the GRS 023-123?
For final polishing, use the GRS 023-120 Yellow Rubber-Bond Diamond Polishing Wheel. GRS lists the 023-120, 023-122, and 023-123 as the diamond-wheel options for polishing and shaping gravers.
