Tyrolit Mounted Points | Vitrified & Resin Bonded Abrasive Points for Precision Deburring
Tyrolit Mounted Points are small grinding tools consisting of an abrasive head permanently bonded to a steel spindle shank, used in straight grinders, flexible shafts, CNC machines, and micromotors for intricate deburring, die polishing, chamfering, and jig grinding. Available in thousands of shapes (ball, cylinder, cone, tree, flame) and in a wide array of abrasive types (aluminium oxide, silicon carbide, ceramic), Tyrolit mounted points are indispensable in tool and die making, moldmaking, aerospace component finishing, and medical device manufacturing. The abrasive head is typically a vitrified or resinoid bonded wheel that is crushed and shaped, then fired to produce a hard, self-sharpening, porous grinding tool that doesn’t burn or load. Tyrolit’s expertise ensures that points maintain their shape for precise corner radii, yet wear progressively to expose new cutting grains. This provides consistent stock removal with minimal vibration. Mounted points are used for operations where larger wheels cannot access—inside intricate EDM cavities, cross-hole intersections, seal grooves, and turbine blade fir tree profiles. The range includes points designed for high-speed steel, carbide, tool steel, ceramics, and glass. By delivering burr-free, smooth surfaces with precision, Tyrolit mounted points reduce hand-finishing labor and improve part quality in demanding industries.

Exceptional Shape Retention for Intricate Profiles
Vitrified bonds maintain the exact wheel form even under high pressure, enabling consistent rounding of small radii and chamfering of sharp edges without reshaping the tool.
Self-Sharpening Vitrified Structure
The porous bond continuously sloughs away dull grains, presenting fresh, sharp abrasive to the workpiece, so the point cuts cool and fast until it is fully consumed.
Universal Shank Sizes and Machine Fit
Standard 3 mm, 6 mm, and 1/4” shank diameters enable immediate use in straight grinders, flexible shafts, micromotors, and robotic end-effectors without special collets.
Non-Loading Porous Design
Pores in the vitrified structure carry away swarf and allow coolant flow, preventing the loading and smearing that can occur when grinding aluminium or soft alloys.
Broad Mineral Selection for Any Hardness
Ruby (AlOx) for tool steel, green SiC for carbide and ceramics, diamond for ultra-hard materials; Tyrolit provides the exact abrasive chemistry for the workpiece.
Minimal Vibration for Superior Surface Finish
Precision balance and concentricity between shank and abrasive head eliminate chatter, producing a smoother finish and reducing operator hand fatigue.
Why Toolmakers Worldwide Depend on Tyrolit Mounted Points
Die and mold polishing is an art, but the rough grinding and shaping stages demand aggressive material removal without sacrificing precision. Tyrolit mounted points provide the aggressive cut of a grinding wheel in a miniature, highly controllable form. A cylindrical point can quickly grind a flat gate seal area; a spherical point can deburr a cross-drilled oil passage in an engine block. The consistent, predictable wear means that CNC programs using mounted points don’t need constant offset adjustments. For manual operations, the user experiences less kick-back from misshapen points. Furthermore, Tyrolit’s mounted points are contaminant-free, crucial for the repair and maintenance of medical instruments and food-contact parts where ferrous contamination disqualifies the part.
Selecting Mounted Point Shapes and Grits for Complex Geometries
The standard shapes each solve a problem: ball points for internal spheres and round bottom grooves, cylinder points for flat surfaces and edges, tree points with radius for fillets and relief blending, flame points for tight corners. Grit selection: 46–60 for rapid stock removal, 80–100 for general shaping, 120–220 for fine finishing. Tyrolit provides a Shape and Grit selection guide with actual-size silhouettes, helping toolmakers pick the right point for the feature. For high-speed automated deburring in automotive and hydraulic components, special carbide-bonded or diamond mounted points are available.
