BT40 CNC Tool Holders Clamp Explosion Proof Tool Finger CNC Tool Holder Clip

A BT40 holder should leave its magazine pocket in one movement. This is the plastic finger that makes that happen: a white moulded clamp with a BT40 taper seat, listed for automatic CNC machines and woodworking CNC cutting machines. It clips the holder into the pocket, it is a spare part rather than a tool holder, and the listing carries 10 names for it. It is a wear part, and the hardest part of the order is naming it. 1 piece per order, sizes available on request, price quoted per order.

A tool change that goes wrong usually shows up one of three ways: the holder no longer sits square in the magazine pocket, a cracked finger lets the holder slip as the changer arm swings in, and the failed part cannot be matched because every supplier lists it under a different name. This clamp is the plastic finger that sits between a BT40 magazine pocket and the tool holder.

It is a moulded plastic tool finger, white in the photographs, with a BT40 taper seat. The listing names two applications, automatic CNC machines and woodworking CNC cutting machines, and one job: clip the BT40 tool holder into its pocket so the changer arm can pick it up and put it back without the holder shifting.

The same part carries 10 names in the listing: CNC tool fork, CNC tool finger, CNC tool holder, CNC tool clamp, CNC tool clip, CNC tool holder clip, BT40 tool holder clamp, tool change gripper, BT40 CNC tool holder claw and CNC machining spare part. Buyers search by the name their machine builder used.

Material is plastic, colour white, taper BT, and size is listed as various sizes available. Price is quoted per order. Because this is a wear part, check the taper on the holder, the finger shape on the pocket and the way the changer arm grips.

What each field of the listing means on the machine:

• BT40 taper seat — moulded for the BT40 holder, so it clips the holder the magazine was built around rather than a BT30 or ISO30 body.
• Moulded plastic body — the listing gives 1 material, plastic, in 1 colour, white as the photographs.
• Tool fork, finger, claw — 3 names the listing uses for one profile, which matters when a photo is compared with the pocket in front of you.
• Automatic CNC machines — the application field names automatic machines, so this is the magazine side of the change, not the spindle side.
• Woodworking CNC cutting machines — the second application field, plus tool holders, which is where BT40 holders run.
• Milling, drilling, reaming — 3 operations named in the description; all three holders are clipped into the pocket the same way.
• 10 listing names — fork, finger, holder, clamp, clip, holder clip, BT40 holder clamp, tool change gripper, BT40 claw, machining spare part.
• One clamp per pocket — 1 finger holds 1 holder, so a broken position is a one-part order.
• Various sizes available — the size field is open rather than fixed, so matching is done on the pocket and the finger in hand.
• White, as photographed — colour is a version cue when the pocket is checked against the listing photo.

Once a finger cracks, the two usual fixes are to keep changing tools on a clamp that no longer holds, or to buy a magazine assembly to get one plastic part. This is the third option:

• The pocket keeps its reference. A BT40 seat puts the holder back where the changer arm expects it, so the arm does not need re-teaching after a swap.
• A wear part at wear-part cost. 1 moulded plastic finger, not a magazine pocket assembly and not a tool holder.
• Found by number and by name. 10 names and the BT40 taper are both on the page, so the order matches the words the machine builder used.
• Taper first, photo second. BT40 only: a BT30 or ISO30 pocket takes a different finger, and mixing the two is how a holder ends up sitting away from the seat.
• Plastic at the contact point. The body is moulded plastic, so the face that touches the holder on every change is not a metal jaw.
• One position, one part. A failed pocket is a 1-part purchase, and the other pockets keep their fingers.
• Sized to the pocket. Size is listed as various sizes available, so the measurement comes off the pocket rather than from the model number alone.

A clamp. It is the plastic finger that clips the BT40 tool holder into a magazine pocket so the changer arm can pick it up; the holder and the cutter are separate parts. The listing's Type field reads collet chuck, which is the field text as published, while the part itself is the finger.

Only if your magazine pocket takes a BT40 finger of the same shape. Check three things before ordering: the taper on the holder (BT40), the fork profile against the old finger, and the width and depth of the pocket. A BT30 or ISO30 pocket takes a different part.

Yes. 1 finger holds 1 holder in 1 pocket, so a magazine with 20 pockets carries 20 fingers. A broken position is therefore a one-part order rather than a set.

Moulded plastic, white, as the photographs show. The listing gives 1 material and 1 colour, and the taper is BT with the holder interface at BT40.

It is the product-name term this listing uses for the plastic tool finger. No certificate or standard is stated in the parameters, so treat explosion proof as the listing name rather than a rating, and confirm the requirement with your machine builder before relying on it.

No fixed size is published — the listing says various sizes available. Send the measurement of the old finger, or of the pocket it came out of, and the size is matched to that instead of to the model number.

Automatic CNC machines and woodworking CNC cutting machines, holding BT40 tool holders used for milling, drilling and reaming. Those are the 2 application fields and 3 operations named in the listing.

Yes. The part is supplied as 1 clamp, and price is quoted per order — the listing gives no fixed figure. Send the quantity and the size you need and the price follows the order.
