Woodworking Drill Adapter B-14x40-1 Converter Joint 20mm OD 14mm ID 40mm L

The B-14x40-1 is a quick-release converter joint that mounts a drill bit in a multi boring machine or woodworking drilling system: 20 mm outside diameter, 14 mm inside diameter, 40 mm overall length, 60 g per piece. The collet releases by hand, so a bit change needs no spanner and the head keeps its alignment. Check those three numbers against the unit before ordering. It is a replacement component, not a complete drilling head, packed 2 pcs per plastic box, price quoted per order.

A drill bit change on a boring unit costs more than the bit. In most cabinet shops three things go wrong: the adapter in the head has to come off with a spanner, the spare in the drawer is not the one the unit takes, and a worn adapter lets the bit sit off centre so the hole pattern stops repeating.

The B-14x40-1 woodworking drill adapter removes all three. It is a quick-release converter joint: the 20 mm outer diameter locates in the drilling unit, the 14 mm inner diameter takes the drill bit shank, and the 40 mm overall length sets the stand-off between unit face and bit tip.

The collet opens by hand, so a bit comes out and goes back in without a spanner. Because the adapter stays seated in the drilling unit while the bit is changed, the alignment the unit was set to is kept and the next hole lands where the last one did.

Each adapter weighs 60 g, light enough to stay on the drilling head between changes. It is a replacement component for multi boring machines and woodworking drilling systems, where a drilling pattern is checked every shift. Main application: furniture and cabinet production. Packing is 2 pcs per plastic box; price is quoted per order.

Four numbers define this adapter, and all four can be checked with a caliper.

• 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 adapter in the drilling unit.
• 14 mm inner diameter — the bore that takes the drill bit shank, matched at 14 mm.
• 40 mm overall length — the stand-off between the unit mounting face and the bit tip.
• One code for two dimensions — B-14x40-1 carries the 14 mm bore and 40 mm length, so the fit is checked on the order line.
• 60 g per piece — the complete adapter weighs 60 g, so a spare in the drawer weighs next to nothing.
• Converter joint, not a chuck — the body converts between the drilling unit and the bit interface, so the head stays a separate item.
• Multi boring machine application — made for multi boring machines and woodworking drilling systems, including furniture and cabinet production.
• Replacement component — sold as a drop-in replacement for an adapter that is worn, seized or the wrong size for the unit.
• 2 pcs per plastic box — each box holds 2 pieces, so a spare carries the same B-14x40-1 number.

The choice on a worn adapter is between hunting the right small part and a service call.

• A bit change without a spanner. The collet opens by hand, so the break is the 14 mm bit swap itself.
• The hole pattern stays where you set it. The adapter stays seated while the bit changes, so the 20 mm locating diameter holds the head position.
• Two dimensions on one order line. B-14x40-1 writes the 14 mm bore and the 40 mm length together, so a wrong bore is caught before shipping.
• Nothing added to the drilling head. At 60 g it is light enough to leave mounted, and a spare is no weight at all.
• A spare that is the same part. 2 pcs per box means the second adapter carries the same B-14x40-1 number as the first.
• A head that does not idle. As a replacement component, a worn adapter on a multi boring machine is one 2-piece box from running.
• Made for repeat work. Application is multi boring machines and woodworking drilling systems, where the 14 mm bore has to repeat.
• Priced on the part you need. Quotation is per order, so one adapter and a box of them are priced against the same B-14x40-1 code.

It is a quick-release converter joint that mounts a drill bit in a multi boring machine or woodworking drilling system. 20 mm outside diameter, 14 mm inside diameter, 40 mm overall length, 60 g per piece.

Only if the unit 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 on its own does not confirm anything.

14 mm is the inner diameter and 40 mm is the overall length, with -1 as the variant suffix on this listing. The 20 mm outer diameter is not written in the code, so check it separately against the drilling unit.

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

No. The adapter stays seated in the drilling unit while the bit is changed, so the position the head was set to is kept.

2 pcs per plastic box. The plastic box is the packing unit on this listing, so the quantity you order 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-14x40-1 with the 20 mm seat, 14 mm bore and 40 mm length you need to match, and the quote is written against those numbers.
