Product
A sleeve is only as good as the relationship between its two tapers. Ground in a controlled sequence so the tool ends up where the programme expects it.
Best for
Adapting taper tooling and reaching into deep features
You send
Inner and outer taper sizes, length and retention method
You get back
Sleeves with both tapers ground and concentricity checked
How it starts
Total length reviewed against rigidity before manufacture
The situation
Each interface adds error. Stacking them is convenient once and expensive thereafter.
What you get
Taper reduction sleeves and extension sockets, ground for concentricity.
The machine interface, tool interface and working envelope are checked before manufacture, so sleeves arrive ready to run.
Supplied from range where a standard suits the job, made to order where it does not, or reproduced from your sample where the original is unavailable.
Locating and clamping features are ground and the dimensions governing runout and repeatability are inspected before dispatch.
Repeat orders and modifications are handled in Bengaluru rather than through an import cycle.
A reduction sleeve has a larger external taper and a smaller internal taper so a small-shank tool can run in a larger spindle. An extension sleeve moves the tool further from the spindle. Both depend on concentricity between the two tapers, which is why the grinding sequence matters more than the catalogue number.
Morse-to-Morse reductions in common combinations, extension sockets in a range of lengths, and sleeves with tang or threaded retention. Verified table to follow.
Confirm both tapers, the retention method and the total length against your reach and rigidity needs — a sleeve that reaches but flexes solves nothing.
Hardened steel with both tapers ground in one setup wherever possible, and concentricity checked.

FAQ
The questions engineers and buyers ask before sending a drawing. If yours is not here, ask it directly — you will get an engineer's answer, not a brochure.
Still have a question?
Talk to Anita M.N, Managing Partner, or send the drawing and let the review answer it.
Inner and outer taper sizes, Length or extension required, Retention method (tang or drawbar), Machine and application, Quantity. If you are unsure of any of these, send a photograph of the current holder and the machine nameplate — that is usually enough for us to confirm the rest.
Yes. Variations in length, reach, interface, clamping or tool size are manufactured to order. Fully custom variants go through the custom tool holder process, with a drawing approved by you before manufacture.
Against three things: the machine interface, the tool interface and the working envelope. Where an existing item is being replaced, matching it to your sample or original part number is the most reliable route of all.
Yes. A drawing is manufactured to its stated tolerances; a sample is measured and reverse engineered into a drawing for your approval, and then manufactured.
