Quick Release Converter Joint B-14x40-2 20mm OD 14mm ID 40mm L

Need to change bits on a multi boring head without a spanner? The B-14x40-2 is a quick release converter joint for woodworking drilling systems: 20 mm outer diameter, 14 mm inner diameter, 40 mm overall length, 60 g per piece. The collet opens by hand, and the joint stays seated in the spindle while the bit changes, so the hole pattern keeps repeating. Packed 2 pcs per plastic box, quoted per order. Check the 20 / 14 / 40 mm against the spindle before ordering.

On a multi boring machine a drill bit change costs more than the bit. Three things go wrong in the shop: the adapter in the head has to be loosened with a spanner, the spare in the drawer is a different size, and a joint that no longer seats lets the bit sit off centre, so the hole pattern stops repeating. The B-14x40-2 quick release converter joint is built to remove all three.

It is a woodworking drill adapter that sits between the drilling spindle and the bit. The 20 mm outer diameter locates in the spindle mount, the 14 mm inner diameter takes the bit shank, and the 40 mm overall length sets the stand-off between spindle face and bit tip. All three can be checked with a caliper before the part goes on the machine.

The collet releases by hand, so a bit comes out and goes back in without a spanner. Because the body stays seated in the spindle while the bit changes, the position the head was set to is kept for the next hole.

Each joint weighs 60 g, light enough to stay on the spindle. It is a replacement component for multi boring machines and multi spindle drilling systems in furniture and cabinet production. Packing is 2 pcs per plastic box; price is quoted per order.

Five numbers define this joint, and every one of them can be checked with a caliper before it goes on the machine.

• Quick release collet — the bit comes out by hand, so a drill bit change needs no spanner.
• 20 mm outer diameter — the locating diameter that seats the joint in the drilling spindle mount.
• 14 mm inner diameter — the bore that takes the bit shank, matched at 14 mm.
• 40 mm overall length — the stand-off between the spindle mounting face and the bit tip.
• One code for two dimensions — B-14x40-2 writes the 14 mm bore and the 40 mm length, so the fit is read off the order line.
• 60 g per piece — a complete joint weighs 60 g, so a spare in the tool drawer adds no load to the spindle.
• Converter joint, not a chuck — the body converts between the spindle and the bit interface, so the head stays a separate item.
• Effortless installation — the joint pushes onto the spindle mount, so fitting a replacement needs no setting-up routine.
• Multi spindle application — made for multi boring machines and woodworking drilling systems, including furniture and cabinet production.
• 2 pcs per plastic box — each box holds a pair, so the second joint carries the same B-14x40-2 number.

The choice on a worn joint is between hunting an exact small part and leaving the head idle.

• A bit change without a spanner. The collet opens by hand, so the break in the shift is the bit swap itself.
• The hole pattern stays where you set it. The joint stays seated while the bit changes, so the 20 mm locating diameter holds the head position.
• Two dimensions on one order line. B-14x40-2 writes the 14 mm bore and the 40 mm length, so a wrong bore is caught before shipping.
• Nothing added to the spindle. At 60 g the joint can stay mounted, and a spare costs no weight.
• A spare that is the same part. 2 pcs per box means the second joint carries the same B-14x40-2 number as the first.
• A head that does not idle. A worn adapter is one 2-piece box away from running again, not a service call.
• Made for repeat work. The application is multi boring machines and multi spindle heads, where the 14 mm bore has to repeat.
• Priced on the part you need. Quotation is per order, so one joint and a box of them are priced against the same code.

It is a woodworking drill adapter that mounts a bit in a multi boring machine or multi spindle drilling system. 20 mm outer diameter, 14 mm inner diameter, 40 mm overall length, 60 g per piece.

Only if the spindle takes a 20 mm seat, a 14 mm bit shank and a 40 mm stand-off. Those three numbers decide the fit; the machine brand alone does not confirm anything.

No. The collet releases by hand, so the bit comes out and goes back in without a spanner.

20 mm is the outside diameter that locates in the spindle; 14 mm is the inside diameter that takes the bit shank. They are two different fits on the same joint, so check both.

No. The joint stays seated in the spindle while the bit changes, so the position the head was set to is kept.

60 g per piece, 2 pcs per plastic box. The plastic box is the packing unit on this listing, so quantity is counted in boxes of two.

Just the adapter. It is a converter joint and a replacement component, not a complete chuck, drill head or drilling unit.

Price is quoted per order rather than fixed on the page. Send the code B-14x40-2 with the 20 mm seat, 14 mm bore and 40 mm length you need to match, and the quote is written against those numbers.
