F-20x43.5 CNC Machining Parts Tool Holder Quick Change Chuck Drill Sleeves

Product Description

No need to buy a new chuck to run a different drill: the F-20x43.5 quick change chuck drill sleeve is 20 mm across the outside and 43.5 mm long, and it seats in the CNC tool holder already on the machine. It is supplied as one CNC machining part per sleeve, so a worn sleeve is a sleeve swap, not a holder rebuild. Other sizes in the range are on the catalogue sheet, and size is made to order. Price on request; shipped by air, sea or express.

A tool holder that takes one shank size is a bottleneck in three places. A drill change turns into a chuck change, so the machine waits while someone finds the right adapter. A job arrives with a different drill, and the quick change chuck on the machine no longer takes it. And when a sleeve is worn or lost, the holder sits idle until a replacement lands.

The F-20x43.5 is that replacement part. It is a drill sleeve made for a CNC tool holder as a CNC machining part, with a 20 mm outer diameter and a 43.5 mm overall length. Those two figures decide fit: 20 mm is the diameter that has to seat in the holder, and 43.5 mm is the length that has to clear it. Measure both on the old sleeve and the order is settled.

Because it is one sleeve and not a complete chuck, a worn sleeve is a small swap instead of a holder rebuild. The same catalogue sheet lists the other sizes in the range, and size is made to order, so a holder that runs a non-standard drill is not a dead end.

Supply is quoted per order at the current price, shipped by air, sea or express to suit the quantity and the deadline. Brand: SHUNHONGYU.

Product Features

What the two dimensions and the sleeve-only build do for a holder:

• 20 mm outer diameter — the diameter is the fit figure; measure the old sleeve across the outside and compare the 20 mm.
• 43.5 mm overall length — the second fit figure; a long sleeve sits proud of the holder and a short one never seats.
• Quick change chuck family — listed under quick change chuck, so the sleeve seats where the old one seated without pulling the chuck off the spindle.
• Sleeve only, not a chuck — one part per drill change; the sleeve takes the contact, so the sleeve is what gets replaced.
• CNC tool holder application — supplied for CNC tool holders, and the holder is the second reference when the old part cannot be read.
• Machined as a CNC machining part — the size is cut as a CNC part, so the 20 mm and 43.5 mm can be repeated on the next order.
• Other sizes on the same sheet — the catalogue page lists further sizes in the range, so a holder set can be ordered in one go.
• Size made to order — customisation is supported, so a diameter and length that are not on the sheet can still be supplied.
• Two-figure order form — diameter, length and quantity: three lines are enough for a quote, with nothing guessed.

Product Advantages

What changes on the shop floor once the sleeve is the part that gets replaced:

• A drill change stops being a chuck change. The 20 mm sleeve is the interface, so the holder stays on the spindle and only the sleeve moves.
• The holder stays in service. A worn or lost sleeve is one part to replace, not a 43.5 mm assembly to buy again.
• Fit is decided by two numbers. 20 mm outside diameter and 43.5 mm length can be read off the old sleeve with a caliper, so the order needs no guesswork.
• One source for the range. The same catalogue page covers the other sizes, so a holder set is ordered together instead of one part at a time.
• A non-standard drill is not a dead end. Size is made to order, so a sleeve that is not on the sheet can still be supplied.
• Downtime shrinks to a swap. The sleeve is the part that takes the contact; one spare on the shelf cuts the wait to the time it takes to change it.
• Shipping follows the order size. Air, sea or express, picked by quantity and by how soon the holder has to run again.

Frequently Asked Questions

What size is the F-20x43.5 drill sleeve?

It is 20 mm across the outside and 43.5 mm long. Those are the only two dimensions the part is defined by, and both are on the parameter table above.

Will it fit my CNC tool holder?

Measure the old sleeve first: 20 mm outer diameter and 43.5 mm length. If both match, it is the same size. Send the holder model, or the number stamped on the old sleeve, if you want it confirmed before ordering.

Is this a complete chuck or only the sleeve?

Only the sleeve. The quick change chuck stays on the machine, and the sleeve is the part that is pulled out and replaced.

Do I need a different sleeve for every drill size?

Yes. The sleeve is matched to the drill shank, so a different shank size is a different sleeve. The other sizes in the range are listed on the catalogue sheet.

Can you supply a size that is not on the sheet?

Yes. Customisation is supported, so send the outer diameter and the length you need with the quantity, and the sleeve is made to that size.

What material is it made from?

The material is not stated in the source data, so it is not claimed here. Send the drill and the holder it goes into, and the material is confirmed with the quote.

How is it priced, and how does it ship?

Price is confirmed on request, and shipping is by air, sea or express. Send the size and the quantity, and the quote comes back with the freight option that fits.

What do I need to send with an enquiry?

Three things: the size (20 x 43.5 mm, or the size you need), the quantity, and the drill shank or holder model. That is enough to quote.
