Product Details

The 93-140 to 93-145 range covers several working profiles in one series. The ball and conical models provide different contact shapes, while the large pencil and mushroom stones give buyers additional options for matching the repair area. Model 93-143 is listed with K18, K23 and K36 grades.

Head dimensions and shank diameter serve different purposes. Use the head profile and size to assess the working area, then check the shank against the tool holder. Most models list a 1/4 in (6.3 mm) shank; 93-143 lists a 1/8 in (3.2 mm) shank. Confirm the required abrasive composition, grade and operating speed when requesting a replacement.

Model Differences

93-140: 7/8 in ball profile; 1/4 in (6.3 mm) shank.
93-141: 1-1/4 × 3/4 in conical buffing stone; 1/4 in (6.3 mm) shank.
93-142: large brown pencil stone; head dimensions to be confirmed.
93-143: 2 in (51 mm) catalogue size, K18 / K23 / K36; 1/8 in (3.2 mm) shank.
93-144 / 93-145: 1-5/8 in large mushroom stones, brown / white respectively.

Applications

Localized repair-area preparation

Match the working profile to the area that needs preparation. Ball, conical, pencil and mushroom forms offer different contact shapes for the selected tire-repair procedure.

Replacement mounted stones

Compare both the head dimensions and the shank before choosing a replacement. A 1/8 in shank and a 1/4 in shank require different holder sizes.

Workshop replenishment

Combine the required profiles in one inquiry. Specify K18, K23 or K36 when ordering 93-143, and give separate quantities for the brown and white mushroom models.

Check tool-holder fit and permitted operating speed before use. Select the abrasive grade according to the repair procedure.

Can I specify an aluminum oxide grinding stone?

Yes. Include the required aluminum oxide grinding stone composition and grade in your inquiry. This catalogue names the range Oxide Stones but does not specify the abrasive composition of every model; the material must be confirmed for your selected SKU.

How do I order a mixed selection of oxide stones?

Select the model numbers and quantities in the table. Add the required grade for 93-143 and any head-size requirement for 93-142. AUTOWIN can then check the specification and prepare wholesale pricing.
