M10x45 M10 Thread Screw Quick Release Collet For Drilling Machine

Need to change a drill bit on a boring head without pulling the whole chuck? The C-M8*45 and C-M10*45 quick release collets do it at the bit, not at the spindle. Both are 45 mm long and threaded M8 or M10 to screw straight onto the spindle thread, and both R and L directions are produced. Metal body, high accuracy, low vibration, one piece per plastic tube in a carton box. Buying spare M10 holders in a small quantity is normal practice, and other sizes are cut to order, so ask for a price.

A bit change on a boring head looks like a small job and rarely is one. The operator backs the chuck out, seats the new bit, re-dials the depth reference, and hopes the seat came back where it was. With an M8 head next to an M10 head, the shop keeps two dedicated chucks. Add a reverse spindle and the wrong thread gets ordered.

The C-M8*45 and C-M10*45 quick release collets take that joint apart. Each is a 45 mm thread-mounted holder: the shank screws into the spindle once and stays, and the bit is released and re-seated at the collet in one movement. M8 for C-M8*45, M10 for C-M10*45, both 45 mm long, so one spare fits either head and one depth setting carries over.

The part is metal through, with the thread and bore cut to the high accuracy it is specified at, and it runs with low vibration. Right-hand (R) and left-hand (L) thread are separate part numbers, because a right-hand holder will not take up on a left-hand spindle.

It fits drilling and multi-boring machines in furniture and cabinet production, and it is a consumable-size spare rather than a machine-level purchase. Each piece ships in a plastic tube inside a carton box, so the thread arrives unmarked, and other sizes are cut to order.

What changes at the spindle-to-bit joint on this collet:

• Two spindle threads, one shape — C-M8*45 takes the M8 thread and C-M10*45 the M10 thread; both measure 45 mm overall.
• Quick release at the bit — The shank stays screwed into the spindle, and the bit is released and re-seated at the collet in one movement.
• Right-hand and left-hand — R and L are both produced as standard part numbers, so a reverse spindle is ordered, not improvised.
• 45 mm on both sizes — The M8 and M10 parts share one length, so a line running both heads keeps one spare.
• Metal body and thread — Material is metal, matching the spindle it threads onto, so the joint stays metal to metal.
• High accuracy on the bore — Specified at high accuracy, which decides whether the bit runs true.
• Low vibration — Specified for low vibration, the property that keeps hole spacing even while the head indexes between M8 and M10 positions.
• Direct thread mount — It screws onto the spindle thread with no intermediate adapter, so there is one joint to check, not two.
• Plastic tube, then carton box — One piece per plastic tube in a carton box, so the thread arrives unmarked.
• Drop-in drilling machine part — A spare for spindles that take threaded M8 or M10 holders, with no machine modification.

The usual choice is between buying a second spindle assembly and living with hand-changed bits. A 45 mm holder that stays on the shank removes both.

• A spare holder instead of a spare spindle. Keep one M8 and one M10 holder and the changeover happens at the bit, not at the spindle.
• One setting for both threads. Because both parts are 45 mm long, a line running M8 and M10 heads shares one reach setting.
• Reverse spindles covered by a part number. Order L and the joint is right the first time, instead of a right-hand holder fighting a left-hand thread.
• Fewer lines in the spare-parts drawer. Two part numbers cover the two common spindle threads, so stock stays small and still covers both heads.
• Changeover stays where the operator stands. The bit comes out and goes back at the collet in one movement, so the depth reference set on the head is not disturbed.
• Thread arrives unmarked. One piece per plastic tube inside a carton box means a holder can sit on the shelf until it is needed.
• Consumable-size ordering. This is a spare-part purchase, not a machine purchase, so a maintenance kit can be built without a capital request.
• Sizes beyond the catalogue. Other thread and length combinations are cut to order, so one supplier can cover the second and third spindle on the same floor.

One 45 mm quick release collet with an M10 thread, packed in a plastic tube inside a carton box. The C-M8*45 version is the same part with an M8 thread, so order the one that matches the spindle, not the bit.

Match the spindle thread. Measure or read the thread on the spindle nose: M8 takes C-M8*45 and M10 takes C-M10*45, and both are 45 mm long, so the choice never changes the reach.

Yes, order L. Right-hand (R) and left-hand (L) thread are separate part numbers, and a right-hand holder will not take up on a left-hand spindle.

No. Both C-M8*45 and C-M10*45 measure 45 mm, so the same depth reference works on either head and one spare covers both.

Both words get used for it, and the part is the same. It is a thread-mounted quick release collet, listed under quick change chucks for drilling machines because that is how operators search for it.

Metal. The body and the thread are metal, matching the metal spindle the collet screws onto, so the joint stays a metal-to-metal seat.

Yes. Other sizes are made to order; send the thread and the length you need and the quotation follows.

Send the machine model plus the spindle thread (M8 or M10) and the direction (R or L), and the quote comes back against a confirmed fit.
