ISO30 CNC Tool Holders CNC Collet Chucks ER32 And ER40 For CNC Routers

Need an ISO30 holder that goes straight into an HSD spindle without a new taper or a new nut? These two cover it. ISO30-ER32-50 runs ER32 collets and clamps a shank up to 20 mm (3/4 in); ISO30-ER40-60 runs ER40 on the same taper. Both are 20CrMnTi, nickel plated against rust, balanced to 30,000 rpm at G2.5, and carry an HSD pull stud and clamping nut. 50 mm flange diameter, and they fit Biesse, CNT, DMS, Masterwood, Flexicam, Techno and NEW CNC routers. In stock for quick delivery.

A shop running an automatic tool changer meets the same three things: a taper that has bell-mouthed so runout climbs and the cutter squeals; a replacement that arrives without a nut, so the spindle waits; and a spare with rust on the shank that no longer repeats. These ISO30 holders remove all three.

Both are ISO30 CNC tool holders with a 50 mm flange diameter, the size most woodworking routers are set up around. ISO30-ER32-50 takes ER32 collets and clamps a shank up to 20 mm, 3/4 in; ISO30-ER40-60 takes ER40 collets on the same taper. Each ships with its clamping nut, matched to the thread on the body, so a replacement is one line item, not two.

The body is machined from 20CrMnTi, then nickel plated with an anti-rust finish, so the taper stays bright through a humid workshop and a magazine idle over a shutdown. Both are balanced to 30,000 rpm at G2.5 and carry an HSD pull stud — the part the drawbar reaches for at every change.

They fit routers on the ISO30 taper with HSD spindles, including Biesse, CNT, DMS, Masterwood, Flexicam, Techno and NEW CNC machines. Country of origin is China, and both models are held in stock for quick delivery.

What separates these two from a generic ISO30 spare:

• ER32 interface, 20 mm ceiling — model one clamps shanks up to 20 mm (3/4 in), covering the 1/2 in and 12 mm bits most jobs use.
• Two models, one taper — ISO30-ER32-50 and ISO30-ER40-60 both sit on ISO30, so one spare rack covers both collet sizes.
• 50 mm flange diameter — the body size listed for this holder, the same envelope the fork and gripper on the router were set up around.
• 20CrMnTi body — the alloy named for this part, machined and then nickel plated rather than left as bare steel.
• 30,000 rpm at G2.5 — the balance grade stated for both models, so the holder does not cap spindle speed.
• HSD pull stud — fitted to the holder, matching the stud pattern that HSD-spindle routers draw in at the change.
• Anti-rust, nickel plated — listed for both models, so shelf time does not mean polishing a taper before it goes back in the magazine.
• Clamping nut included — each holder arrives with its nut, so a broken holder is one order, not a thread hunt.
• Cut for HSD-spindle routers — Biesse, CNT, DMS, Masterwood, Flexicam, Techno and NEW CNC machines are the application listed for both models.
• Held in stock, made in China — both models sit in stock for quick delivery; country of origin is China.

The usual choice is between OEM money for one holder and running the worn one until it marks the work. A spare that fits first time removes the choice.

• A change, not a rebuild. ISO30 taper, 50 mm flange, HSD pull stud — the three fits your machine expects, so the change position stays where it was set.
• The nut is already there. Nuts ship with the holder, so a 20 mm spare is not a second order and a second wait.
• One taper, two collet families. ER32 to 20 mm / 3/4 in on ISO30-ER32-50, ER40 on ISO30-ER40-60 — two carriers, one spare rack.
• Balance does not limit the spindle. 30,000 rpm at G2.5 is quoted for both models, so the holder is not what holds the router back.
• Storage stops being a risk. Nickel plating means a holder that sat a season still takes a 20 mm shank without being polished first.
• Steel named on the page. 20CrMnTi is the alloy listed for both models, so a quote can be checked against a material, not a description.
• A price for your quantity. Listed as contact us, so the number comes back against model, quantity and delivery mode in one reply.

Woodworking routers on the ISO30 taper with HSD spindles. Biesse, CNT, DMS, Masterwood, Flexicam, Techno and NEW CNC machines are the application named for both models, and the pull stud is HSD — so a magazine already set up for HSD studs takes the holder without a change.

Match it to the collet you already run. ISO30-ER32-50 takes ER32 collets, ISO30-ER40-60 takes ER40 collets; both mount on the ISO30 taper with a 50 mm flange, so the collet series is the only thing that decides which one you order.

20 mm, or 3/4 in. That is the shank capacity quoted for the ER32 interface on ISO30-ER32-50, which covers the 1/2 in and 12 mm router bits most jobs are cut with.

30,000 rpm, balanced to G2.5. That grade is stated for both ISO30-ER32-50 and ISO30-ER40-60, so the holder is not the part that caps spindle speed.

20CrMnTi. It is the alloy listed for this part, with a nickel plated, anti-rust finish over it so the taper stays bright between jobs.

Yes. Clamping nuts are supplied with the holder, matched to the thread on the body, so the replacement is one line item and there is nothing else to order.

HSD. Both models carry an HSD pull stud, so they suit ISO30 magazines and grippers that take the HSD stud pattern rather than a BT or HSK one.

Yes, both models are held in stock for quick delivery. Price is quoted per order rather than published, so send the model and the quantity and the figure comes back with the delivery option.
