Start with the operation, not the catalogue
Before comparing shapes, describe what the point has to do: remove weld metal, deburr an edge, blend a radius or finish inside a bore. The operation sets how much material has to come off and how much control the operator needs.
Once the operation is clear, the shape follows. Conical and dome nosed profiles suit blending and localised work; other profiles suit flat or shouldered surfaces. If a point already works acceptably, the fastest route is to reorder against that same specification.
Record the shape reference you already use
Shape designations such as A11 are the common shorthand between buyers and suppliers. If your stores record a shape reference, quote it. If not, a clear photograph next to a scale, plus the shank diameter, is usually enough for a supplier to identify an equivalent.
- Shape reference, if you have one
- Head dimensions, roughly measured is fine to start
- Shank diameter and usable shank length
- Grade, grit and bond, if printed on the point or its box
Match the point to the machine
The tool holding the point matters as much as the point itself. Note the machine or handpiece, its speed range and whether it is air or electric driven. Speed limits are set by the point manufacturer, so always work within the rating stated for the specific point you buy.
Confirm consistency for repeat supply
For recurring requirements, agree the specification in writing once and reference it on every order. That is how a monthly schedule stays predictable: the same confirmed detail, batch after batch, rather than a fresh interpretation each time.
What to send when you enquire
The more of the following you provide, the fewer rounds of clarification before a quotation.
- Shape reference or a photograph of the point in use
- Shank diameter and head dimensions
- Grade or grit currently used
- Material and operation
- Machine and its operating speed
- Quantity required, or monthly consumption
- Delivery city and PIN code
This guide is general purchasing guidance from a supplier, not a safety standard. Always follow the speed rating, mounting instructions, guarding and personal protection requirements published by the manufacturer of the specific point, together with your own plant safety procedures.
