BT40 CNC Tool Holders Plastic Tool Forks Tool Finger For Automatic CNC Machine

Need a BT40 tool fork that lets an automatic tool changer load holders without a wobble? This is the replacement tool finger, part number 40194149, moulded in white plastic for BT40 holders on woodworking CNC cutting machines and machining centres. It sits in the magazine pocket, straddles the holder groove and lets the changer pick and return the tool. Various sizes are available, so the size is matched to the pocket instead of guessed. Price is quoted per order.

Three things stop an automatic tool changer: a fork cracked at its seat, one pocket sitting lower than the others, and a replacement that arrives with the wrong profile so the holder hangs loose. Each one parks the spindle, and none of them announces itself until the changer is mid-cycle. A spare fork in the cabinet is cheaper than the wait that follows.

The BT40 plastic tool fork, part number 40194149, is the consumable that holds a BT40 tool holder in the magazine. It is moulded in plastic, supplied white as shown in the photos, and shaped as a two-finger fork: the fingers straddle the holder groove, the fork base sits in the pocket plate. The taper is BT, and the model is listed as BT40 Tools, so the part belongs to a BT40 magazine rather than a mixed set.

It is used with CNC machining centres and specified for woodworking CNC cutting machines — nested routers, drilling centres and lines that change tools every few seconds. The fork is a wear part by design, and a plastic seat is far less likely to score the holder taper than a metal jaw.

Fork sizes vary. Photograph the fork you are removing and note the seat height and the finger opening, then quote 40194149 with your enquiry. Price is quotation-based, so quantity, size and destination decide it.

What the part is, in the order a buyer checks it:

• Part number 40194149 — the number to quote on a repeat order, so the pocket receives the same profile twice rather than a look-alike.
• BT40 taper seat — sized for BT40 holders; it is not interchangeable with BT30 or HSK pockets, so check the taper on the machine first.
• Moulded plastic body — plastic instead of steel, so the fork takes the wear and the hardened holder taper stays unmarked.
• Two-finger profile — the fingers straddle the holder groove while the fork base sits flat in the pocket, so the changer arm meets the same seat.
• White finish — white as shown in the photos, which lets a hairline crack or resin build-up show on a routine walk-round.
• Automatic machine fit — used with CNC machining centres and their tool changers, not with hand tooling.
• Woodworking CNC application — specified for woodworking CNC cutting machines, including router and drilling centres.
• Various sizes — more than one fork profile is listed, and the match is made from your pocket measurement or a photo of the worn fork.
• One spare-parts catalogue — HSK40E and HSK63F tool holder forks and ER11 spring collet chuck holders are listed alongside, so a magazine refit is one purchase order.

A fork is a small part with a large stopping cost. The usual choice is to wait for a shipment, or to run a cracked fork until the changer alarms. Stocking the part removes both.

• A spare on the shelf ends the wait. One cracked fork is enough to park a machining centre, and a fork is a consumable rather than a capital item, so holding two is normal practice.
• The taper stays unmarked. Plastic contact in the pocket protects the holder taper, and an unmarked taper keeps runout where the tool grinder set it.
• Damage is visible in seconds. White moulding shows the hairline crack that a dark fork hides, so a walk-round catches the fork before the changer does.
• Repeat orders come back identical. Quote part number 40194149 and the same profile is supplied, so the replacement does not need re-fitting.
• Sizes are matched, not guessed. Send the pocket measurement or a photo of the old fork; several sizes are listed and the nearest one is quoted against it.
• One supplier for the whole pocket. BT40 forks, HSK tool holder forks and ER collet chucks come from the same catalogue, so a magazine refit is one enquiry.
• Specified for woodworking machines. The application list is woodworking CNC cutting machines and tool holder work, which is where plastic forks are consumed fastest.

BT40 automatic CNC machines. It is specified for woodworking CNC cutting machines and used with CNC machining centres that change tools from a magazine, so it is a magazine part rather than a spindle part.

Plastic. The body is moulded plastic in white, as shown in the photos, and the item is listed as BT40 Tool Holder Forks under model BT40 Tools.

Match it to the pocket you are replacing, not to the machine model. Sizes are listed as various sizes available, so send the seat height, the finger opening and a photo of the worn fork with your enquiry.

Only when the profile matches the pocket. The fingers grip the holder groove, so a fork from another taper or a worn pocket lets the holder sit low; compare the seat height with the fork you take out.

White is the supplied colour, exactly as shown in the product photos. On the machine the light colour also makes cracks and swarf build-up visible during a walk-round check.

Price is quoted per order. Quantity, fork size and destination go into the quote, so a single trial piece and a full magazine set are both quoted on request.

Yes. The same catalogue lists HSK40E and HSK63F tool holder forks and ER11 spring collet chuck holders, so a mixed magazine can be ordered together.
