Product
Vertical turret lathes take deep, interrupted cuts on components that are expensive to scrap. The holder has to stay put. Ours are matched to your turret slot, cutting direction and reach.
Best for
Heavy facing, turning and boring on vertical turret lathes
You send
Turret or ram details, tool shank, reach and cutting direction
You get back
Holders matched to your machine, inspected before dispatch
How it starts
Compatibility confirmed before manufacture
The situation
On a vertical lathe, the consequences of a marginal holder show up on a component that already has many hours in it.
What you get
Holders for vertical turning, facing and boring, matched to your turret and tooling.
The machine interface, tool interface and working envelope are checked before manufacture, so holders 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 VTL tool holder mounts the cutting tool on the ram or turret of a vertical turret lathe and holds it rigidly under the heavy, interrupted loads that come with large-diameter turning and facing. CMTA manufactures VTL holders for HMT and other vertical lathes used in heavy engineering, machine tool building and large-component job shops.
Straight, offset and angled holders for turning, facing and boring, in the shank sizes used on common VTL rams and turrets. The verified size table is published once confirmed by CMTA; in the meantime, send your turret or ram details and we will confirm the fit directly.
Fit is defined by the ram or turret slot, the clamping method and the tool shank. Reach and offset follow from the workpiece diameter, the chuck and the feature being cut, so the holder clears the job without carrying more overhang than the cut requires.
Holder bodies are made from alloy steel, heat treated and ground on the locating and clamping faces, with critical dimensions inspected before dispatch.

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.
Machine interface and turret or ram slot details, Shank or tool geometry, Reach required, Cutting direction, Clearance to chuck and workpiece. 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.
