Product description

HSK-A63 / HSK-A100 ER collet chuck DIN 69893 (HSK63A, HSK100A): ER11, ER16, ER20, ER25, ER32, ER40, ER50

ER collet chuck with an HSK-A63 or HSK-A100 taper to DIN 69893 (ISO 12164). A tool with a cylindrical shank is clamped in an ER collet, which is tightened by the holder nut.

HSK-A63: ER11, ER16, ER20, ER25, ER32 and ER40 collets, lengths from 75 to 200 mm (T versions with a neck: 160 and 200 mm, code ending in LT), A, mini M and UM nuts. HSK-A100: ER16, ER20, ER25, ER32, ER40 and ER50 collets, length 100 mm (ER50: 120 mm), A and UM nuts. Select the variant when purchasing.

Applications

clamping drills, end mills and reamers with cylindrical shanks in ER collets
drilling, milling and reaming on CNC milling machines and machining centres with an HSK-A63 or HSK-A100 spindle
one holder for many shank diameters: only the ER collet is changed (clamping range in the table)

Specification

Taper type	HSK-A63 or HSK-A100 (DIN 69893 / ISO 12164), according to the variant code
Tool clamping	ER collets to DIN 6499: ER11, ER16, ER20, ER25, ER32, ER40, ER50
Nut	A, mini M or UM, according to the variant code
Clamping range	1–34 mm, depending on the ER size (dimension table)
Holder runout	≤ 0.003 mm
Balance grade	at least G6.3 (many pieces are balanced to G2.5 at 25,000 rpm: ask us and we will check the label of the specific piece)
Coolant	AD version (central coolant supply)
Material	case-hardened alloy steel (case depth 0.8 ± 0.2 mm)
Hardness	HRC 56–60
HSK taper	taper tolerance < AT3, surface roughness Ra < 0.2 µm
Standard	DIN 69893 (taper), DIN 6499 (ER collets)
Included	holder with nut; ER collets are selected separately

Balance grade: at least G6.3. Many HSK-A holders of this type (HSK-A63 and HSK-A100) are balanced to G2.5 (more precise). If you need G2.5 for high spindle speeds, write to us before purchasing — we will check the label of the specific piece before shipping.

Coolant: AD version. If your spindle supplies coolant in a different way, write to us before purchasing.

D – body diameter, D1 – nut diameter, L – length from the HSK flange face (spindle side) to the end of the nut, M – thread in the holder bore for the stop screw (“–” – no thread), clamping range – shank diameters covered by ER collets of the given size.

In T versions: D – neck diameter, D2 – largest diameter of the tapered section, L1 – length of the neck with diameter D, α – angle of the tapered section.

Read the complete designation of the selected variant. For example, HSK63A-ER32UM-100L means an HSK-A63 taper, ER32 collets, UM nut and length L = 100 mm; HSK100A-ER32UM-100L is the same holder with an HSK-A100 taper. A, M and UM are different nuts.

How to select

Check whether the spindle has an HSK-A63 or an HSK-A100 interface and select a variant with that taper: the code starts with HSK63A or HSK100A.
Select the ER size for the tool shank diameter: the clamping range is given in the table (e.g. ER32: 3–20 mm). The collet is selected for the specific shank diameter.
The mini M nut has a smaller diameter (D1 in the table) than the A and UM nuts.
A shorter holder gives higher rigidity, a longer one gives greater reach.

Before installing the collet or replacing the cutting tool, thoroughly clean the nut thread and the collet surface, then apply grease. Failure to clean and lubricate these surfaces may damage the nut thread.

FAQ

Will it fit my machine?
The holder has an HSK-A63 or HSK-A100 shank to DIN 69893 (ISO 12164), according to the variant code. Before purchasing, confirm the form and size of the spindle interface in the machine documentation. HSK-A, HSK-E and HSK-F are different shank forms, and 63 and 100 are different sizes, so the designation “HSK” alone is not sufficient to confirm the selection.

Are ER collets included?
No. The holder comes with its nut; select the ER collet separately for the tool shank diameter.

How do the A, M and UM nuts differ?
They differ in design and outer diameter (D1 in the table). The variant code states which nut the holder has.
