Mounted Point Selection — Quick Reference
Mounted points are shank-mounted abrasive grinding tools for die grinders, rotary tools, and flexible-shaft machines — internal grinding, deburring, weld blending, die finishing in confined spaces. Selection turns on shape (matches contour to access), abrasive grade, and shank size.
| Shape Code | Profile | Best For |
|---|---|---|
| W (Cylindrical / Square Edge) | Straight cylindrical body | General internal grinding + surface blending — workshop default |
| A (Spherical / Ball) | Ball-shaped | Radius grinding, concave + spherical surfaces |
| B (Cone / Pointed) | Conical body to point | Tight angles, V-groove finishing, weld root work |
| C / D (Tapered) | Tapered diameter along length | Internal tapered features, draft angle grinding |
| E (Cylindrical with Rounded End) | Cylinder + ball end | Blending corners in pockets, transition radii |
| K (Cup / Concave) | Concave grinding face | External rounding, OD profile work |
| Dressing Stones | Specific dresser geometry | Truing + dressing larger grinding wheels |
Abrasive: Aluminium Oxide (brown — standard, A-grade) | Aluminium Oxide pink (PA — tool steel, finer + cooler) | Silicon Carbide (green — carbide tools, non-ferrous, cast iron). Shank sizes: 3mm + 6mm = die grinder standard. RPM rating: always match the point's MAX RPM to your tool — exceeding rating = explosive failure. Brands: Pferd, Norton. Companion: abrasives, die grinders.
Mounted Points
Mounted points are shank-mounted abrasive grinding tools used in die grinders, rotary tools and flexible-shaft machines for internal grinding, deburring, weld blending, die finishing and surface preparation in confined areas. AIMS Industrial stocks a comprehensive range from Pferd and Norton.
Shapes and Profiles
- Cylindrical (W shape) — general-purpose internal grinding and surface blending
- Spherical / Ball (A shape) — for radius grinding and concave surfaces
- Tapered and Cone shapes — for accessing tight angles and internal profiles
- Dressing stones — for truing and dressing grinding wheels
Pferd and Norton
Pferd mounted points are available in aluminium oxide (brown) with mixed hardness grades and standard N-hardness, in individual packs and assorted sets. Norton mounted points include aluminium oxide A-shape (pink) and W-shape options for precision die and mould work. Both brands offer consistent grit quality suited to hardened steels, cast iron and general metalworking.
Abrasive and Grit Selection
Aluminium oxide suits hardened steels and cast iron. For finer finishing work, use higher grit numbers; for aggressive stock removal, use coarser grades.

People Also Ask — Mounted Points
Q: What is a mounted point used for?
Mounted points are small abrasive grinding stones bonded to a metal shank — used in die grinders, pneumatic micro-grinders, or rotary tools to grind, deburr, blend, and shape metal in tight spaces where a full-size grinding wheel doesn't fit. Common in toolmaking, mould and die finishing, weld dressing, and general workshop deburring of holes, recesses, and internal features.
Q: What shape mounted point should I use?
Cylindrical (straight) for flat work and internal edges, conical for vee-grooves and angled clearances, ball for radius work and contour grinding, tree-shape for blending compound surfaces, wheel-shape for slot grinding. Standard ISO shape codes (W164 cylindrical, W205 conical, etc) cross-reference between manufacturers — match the shape to the work geometry.
Q: What grit and bond should I choose?
Coarser grit (24-46) for heavy stock removal, medium grit (60-80) for general work, fine grit (100-180) for finish blending. Aluminium oxide bond is the workshop default — works on most steels and general metals. Silicon carbide for harder materials like cast iron and stone. Ceramic for hardened tool steel and stainless. Match grit and bond to material and removal rate.
Q: What's the maximum safe speed for a mounted point?
Every mounted point has a maximum RPM marked on the package or shank — exceeding this can shatter the abrasive at the rim and send fragments at high velocity. Larger diameter points have lower max RPM than smaller ones. Standard die grinders run 20,000-30,000 RPM unloaded — match the mounted point's rated RPM to your grinder's actual speed. PPE (eye and face protection) is mandatory.
Q: How long does a mounted point last?
Highly variable — depends on material removal rate, grade of the stone, and how aggressively it's used. A workshop point on light deburring can last weeks; the same point on heavy weld dressing in tough steel may wear in a single shift. Replace when the stone has worn down close to the shank (safety risk) or when the cutting action is no longer effective. Keep a kit of common shapes and grits to avoid running out mid-job.
