Consistent finishes and true running give workshop operators confidence during toolmaking and sharpening. Is the Poltava Diamond Tools Straight Abrasive Diamond Grinding Wheel the right staple for your bench?
⚡ At a Glance
- • Cutting Quality: Consistent material removal and predictable finish using 200/160 micron (70 grit) diamond abrasive
- • Best for: Toolmakers, small workshops and grinders working on carbide tooling and precision parts
- • Not ideal for: Applications outside precision machining, such as decorative woodworking or non-abrasive polishing
Resin-bond diamond wheel in a 5-inch format with a 32mm central hole and 10mm width. Suited to machining cylindrical and conical surfaces, apertures, recesses and sharpening carbide tools.
True, repeatable rotation – thanks to accurate runout and stable construction
User feedback reports the wheel runs true with accurate performance, indicating low runout and stable concentric rotation during use. Stable rotation reduces vibration and helps maintain consistent contact between abrasive and workpiece.
Predictable cutting behaviour produces uniform finishes and reduces the need for rework, which saves time during tool sharpening and small-batch machining.
Balanced material removal – with 200/160 micron (70 grit) diamond and resin bond
The listed 200/160 micron sizing corresponds to a mid-coarse, 70-grit abrasive; the resin bond holds diamond grains securely while allowing controlled wear. That combination moderates cutting aggressiveness and surface finish.
Mid-coarse grit removes material efficiently without producing an overly rough surface, making the wheel practical for sharpening and finishing carbide tools.
Compact workshop fit – with a 5-inch diameter, 32mm hole and 10mm width
A 125mm diameter and 32mm bore suit common bench grinders and setups that accept 1.26-inch mounting holes, while the 10mm width gives a usable face for straight-profile machining. Type 1A1 indicates a straight abrasive wheel profile.
Easily mounted on standard small grinders, the wheel handles apertures, cylindrical surfaces and end-face work without requiring large machinery.
