HSK40E Tool Holder Forks CNC Tool Holder Clips For HSK 40E Collet Chucks

Need to replace a cracked fork clip that carries HSK 40E holders through an ATC magazine? The HSK 40E Tool Fork Clips, item 40194582, are that spare: reinforced anti-explosion POM plastic in black, a C-shaped cradle with 2 curved jaws that wrap the holder groove, and 4 fixing points — 2 plain bores plus 2 brass threaded inserts. They fit HSK 40E collet chucks on CNC machining centres, clamp with high force, ship from Foshan, Guangdong, China, and are quoted per order.

A dropped HSK 40E holder usually gives no warning. Late ordering brings three faults: a slack jaw lets the holder sit off its seat, a fork drilled for another arm arrives with holes that miss the bolts, and a metal jaw face scores the shank on every slide. Each one stops the spindle mid-cycle.

The HSK 40E Tool Fork Clips are the black polymer spare that carries an HSK 40E holder between tool changes. The working end is a C-shaped cradle with 2 curved jaws that wrap the holder groove, so the holder hangs on both sides, not at one pinch point. The opening is cut for the 40 taper of HSK 40E collet chucks — the HSK (Hohl-Schaft-Kegel) hollow shank system.

The body is reinforced anti-explosion POM plastic, black through the full section, so a crack shows as a light line rather than hiding under paint. The mounting face carries 2 plain bores and 2 brass threaded inserts — 4 fixing points from one moulding, bolt thread in brass, not plastic. Ribs behind the cradle carry the high clamping force into the base.

Application is CNC machine work: HSK 40E changes on machining centres, then the milling and drilling that follow. Item 40194582 stays the reference on the quotation and the packing. Colour is black, delivery place is Foshan, Guangdong, China, and price is quoted per order.

Every line below can be checked against the fork in your hand or the arm it bolts to.

• HSK 40E fit — the cradle is cut for the 40 taper of HSK 40E collet chucks, so it will not seat an HSK 50 or HSK 63 holder.
• Two curved jaws — a C-shaped opening with 2 moulded jaws that wrap the holder groove on both sides, instead of one pinch point.
• Four fixing points — 2 plain bores plus 2 brass threaded inserts give the arm 4 bolt positions from a single moulding.
• Brass, not a plastic thread — the bolt thread runs in the 2 inserts, so a worn thread is a bush to renew, not a fork to scrap.
• Reinforced anti-explosion POM — the listed material, black through the section, so a cracked jaw reads as a light line.
• Explosion-proof body — the property stated for this fork: a polymer face meets the holder taper, 0 metal jaws on the shank.
• High clamping force — specified as high for this fork, carried into the base by the moulded ribs behind the cradle.
• Ribbed back — a gusset grid behind the cradle spreads that load across the whole mounting face.
• One model, one colour — black POM for HSK 40E only, so a re-order is 1 line on the purchase sheet, not a variant guess.

A slack fork leaves two bad choices: wait on a machine-brand spare, or keep cycling and score the holder. A bolt-on clip removes both.

• The cheap part fails. The jaw is anti-explosion POM, so an impact goes into a fork you can re-order, not into a holder you cannot repair on site.
• Bolts go back where they came from. 2 bores and 2 brass inserts reuse the arm's own fixings — no redrilling, no adapter plate.
• Wear lands in the brass. The thread sits in the 2 threaded inserts, so the plastic body stays serviceable after years of tool changes.
• A fault you can see. The body is black end to end, so a cracked jaw shows before a holder drops out of the magazine.
• One number to stock. 40194582 is the reference on the quote, the packing slip and the next order.
• Explosion-proof by material. The property sits in the POM body, not in a coating that chips off at the jaw.
• A swap, not a rebuild. Bolts out, fork off, fork on, bolts in — no machining and no setting gauge.
• One holder family, no guessing. The part is cut for HSK 40E only, so the 40 taper decides the order, not the machine brand.

Yes, if the holder is HSK 40E. The cradle is cut for the 40 taper of HSK 40E collet chucks, and the item is listed for that holder family only — an HSK 50 or HSK 63 holder takes a different fork.

Yes. Tool holder fork, tool holder clip, fork clip and gripper are the names buyers use for the same spare here: one black POM moulding with 2 curved jaws and a bolt-on base, item 40194582.

Reinforced anti-explosion POM plastic, supplied black through the full section. The only metal in the part is the 2 brass threaded inserts in the mounting face.

Because the anti-explosion property sits in the body material. The face that touches the HSK 40E holder is polymer, so no metal jaw runs against the shank on every tool change.

With the arm's own bolts, through 4 fixing points: 2 plain bores and 2 brass threaded inserts. Take the bolts out of the old fork and they go straight back into the new one.

No. This fork is cut for the 40 taper only, so HSK 50 and HSK 63 holders need their own fork shapes and are not covered by item 40194582.

It does, for as long as the jaw faces are intact. Clamping force is specified as high for this fork, the ribs behind the cradle carry it into the base, and the black body makes a worn or cracked jaw visible.

Send the quantity and the holder model and we quote per order. Delivery place is Foshan, Guangdong, China, and every order is checked against the HSK 40E taper and the 4 fixing points before it ships.
