HSK63F ER40 CNC Tool Holders Precise ER32 Collet Holder For Woodworking Machine

Need a collet holder that seats on an HSK63F spindle nose and covers the shank sizes on your bench? This range runs three collet families — ER20, ER32 and ER40 — on one HSK63F taper, in 93 mm and 103 mm overall lengths with 50 mm and 63 mm outer diameters. Bodies are carbon steel with a silver, anti-rust finish. Accuracy and clamping force are both listed as High. Codes: HSK63F-ER20, HSK63F-ER32, HSK63F-ER40, plus HSK63F-ER32-70 and HSK63F-ER40-80.

A shop cutting on an HSK63F spindle usually hits the same three things: a holder on a different taper that will not enter the spindle nose, a collet family that does not cover the shank in the drawer, and a holder that lets the cutter drift so engraving depth changes between parts. This range clears all three from one taper.

These are HSK63F collet chucks for woodworking CNC engraving machines. Model codes are HSK63F-ER20, HSK63F-ER32 and HSK63F-ER40, with HSK63F-ER32-70 and HSK63F-ER40-80 listed as sized versions; other models are also available. Because ER20, ER32 and ER40 share one HSK63F interface, a detail bit and a surfacing cutter come off the same spindle without a second holder family.

The body runs 93 mm or 103 mm overall, with an outer diameter of 50 mm or 63 mm. Those two figures decide the fit: length eats into the Z travel left for deep pockets, and outside diameter must clear the fork that lifts the holder out of the carousel.

Body is carbon steel in a silver finish, listed with anti-rust properties — useful where coolant and damp chips sit on tooling all day. Accuracy is listed as High and clamping force as High; these are the grades on the sheet rather than micrometer figures, so ask for the inspection number if your process needs one.

What separates this from a holder picked out of a mixed drawer:

• One taper, three collet families — ER20, ER32 and ER40 all mount on the HSK63F interface, so three shank families are fed from one spindle.
• Five codes on the sheet — HSK63F-ER20, HSK63F-ER32, HSK63F-ER40, HSK63F-ER32-70 and HSK63F-ER40-80, so the code you order matches the collet you run.
• 93 mm and 103 mm overall — two body lengths: the short one leaves Z travel for pockets, the long one reaches past a tall fixture.
• 50 mm and 63 mm outside — measured on the body, so nut and fork clearance is checked with a caliper before it goes in the carousel.
• Carbon steel, silver, anti-rust finish — the material on the spec sheet for a part clamped many times a shift, with anti-rust properties listed for coolant work.
• Accuracy listed High — a stated grade on the sheet, so the figure can be checked against the part you receive.
• Clamping force listed High — that is what keeps the collet shut on the shank through an interrupted cut.
• Standard size, more on request — other models are available if the 93/103 mm pair does not cover your machine.
• Woodworking CNC application — listed for CNC machine use on woodworking engraving work, softwood through hardwood.

Buying a CNC holder usually means two bad options: wait for the exact model, or take what fits and shim around it. At 50/63 mm outside and 93/103 mm long, this range removes that decision.

• One order, three collet families. ER20 through ER40 on the HSK63F interface means the small detail bit and the surfacing cutter stay on one spindle.
• Fit checked with a caliper, not a guess. 93/103 mm length and 50/63 mm diameter are on the sheet, so fork clearance and Z travel are measured before ordering.
• Accuracy you can hold the supplier to. High is a stated grade, so the part that arrives can be checked against the figure it was sold on.
• Grip stated, not implied. Clamping force is listed as High — the property that keeps the collet shut on the shank instead of letting the cutter drift mid-pass.
• A body that survives coolant. Carbon steel with an anti-rust finish, so damp chips sitting on tooling do not start a corrosion ring on the taper.
• Repeatable reorders. One model code — HSK63F-ER20, HSK63F-ER32 or HSK63F-ER40 — reproduces the holder you already have, so the second one fits like the first.
• Room to ask for another size. Other models are available, so the 93/103 mm pair is a starting point rather than a wall.

Yes. The holders are built for the HSK63F interface, which is the taper named on every model code in this range. Check the spindle nose for its HSK marking before ordering; a different HSK size will not seat.

Order the collet series your shank and your existing collet set use. The three codes cover ER20, ER32 and ER40 on the same HSK63F taper, and the two sized versions HSK63F-ER32-70 and HSK63F-ER40-80 are the ones listed with a length code. If the shank you run is not covered, ask before you buy.

Yes, it matters. Overall length is 93 mm or 103 mm, and that length is what comes off the Z travel left for deep pockets; outer diameter is 50 mm or 63 mm, which has to clear the fork that lifts it out of the carousel.

Carbon steel with a silver finish, and the sheet lists anti-rust properties. That is a finish property, not a promise against a wet chip bed — wipe the taper before it goes back in the spindle.

High — that is the grade stated on the spec sheet. The sheet gives a grade rather than a micrometer tolerance, so if your process needs a runout number, ask for the inspection figure with the quote.

Clamping force is listed as High, and the holder is listed for CNC machine use, which is the application a slipping holder breaks first. Seat the collet in the nut before the holder goes into the spindle, then torque the nut to your own setting.

Yes. Sizes are listed as standard, other models are also available, and the site states you can contact the supplier if you cannot find the size you want. Give the spindle taper, collet series and overall length you need.

Price is quoted per order — the listing shows Contact us for a quote rather than a figure. Send the model code, the quantity and the collet series you run, and the quote comes back against that combination.
