Product
For deep and large holes, taper-shank drills and reamers remain the most economical tooling in the shop. These adaptors mount them properly on the machine you actually have.
Best for
Deep or large holes using taper-shank tooling
You send
Morse taper size, tool type, hole depth and machine interface
You get back
Adaptors with internal and external tapers ground
How it starts
Retention method and length confirmed before manufacture
The situation
Tapers are self-holding until they are damaged, and then they fail in ways that are easy to misdiagnose.
What you get
Morse taper holders and adaptors for drills, reamers and boring tools.
The machine interface, tool interface and working envelope are checked before manufacture, so adaptors 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.
MTA and MTB holders adapt Morse taper shank tools to the turret or spindle of lathes, VTLs and machining centres, with tang or drawbar retention. They are used wherever taper-shank drills, reamers and boring tools are the sensible tooling choice for deep or large holes.
Morse taper sizes from small to large, with turret-shank, straight-shank and spindle-taper mounting. The verified table follows CMTA's confirmation.
Match the Morse taper of the tool, the retention method — tang or threaded — and the mounting on your machine, then confirm length against hole depth and clearance.
Hardened alloy steel, with internal and external tapers ground and runout checked between them.

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.
Morse taper size, Tool type and shank, Depth of hole, Work material, Machine and turret or spindle interface. 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.
