2-031-95-4491 BORING SPINDLE VERR. HUB60 D28 KPL For Homag CNC Machine

Looking for the vertical boring spindle that fits the Homag Weeke BHX 500 drilling head? This is Homag part number 2-031-95-4491, also written 2031954491, marked HUB=60 / D=28 KPL on the unit. It takes the factory spindle position in the BHX 500 head, so a worn spindle is unbolted and refitted rather than re-machined. Supply is Shunhongyu, price quoted per order, one spindle per position. Confirm HUB=60 and D=28 KPL against the spindle you are removing before you order.

A shop running a Homag Weeke BHX 500 usually hits the same three problems once a drilling unit starts to wear: a spindle that no longer holds hole position, a machine sitting idle while a replacement is hunted down, and a part number nobody can match to the right unit. This spindle is the direct replacement for 2-031-95-4491.

The 2-031-95-4491 BORING SPINDLE VERR. HUB=60/D=28 KPL is the vertical boring spindle that carries and drives the drill bit in the Weeke BHX 500 drilling head. Its hub is marked HUB=60 and its bore D=28 KPL, the two markings that identify the correct variant in the Homag parts list. Order the wrong hub size or bore and the spindle will not seat in the head, whatever the part number says.

Because the spindle is catalogued under Homag number 2031954491, written 2-031-95-4491 on the unit, it takes the factory position in the BHX 500 head, so a swap is an unbolt-and-refit job rather than machine work. It is one of the drill spindles in the vertical boring unit that drills cabinet, furniture and panel holes.

Each hour the head is down is an hour of panels not drilled, so the number that matters is holes per shift, not the wording on a brochure. Check HUB=60 and D=28 KPL against the spindle you are removing before you order.

What separates this spindle from a generic drill spindle is fitment and identification, not marketing language:

• Direct fit for the Weeke BHX 500. The spindle is catalogued for the Homag Weeke BHX 500 drilling head, so it takes the factory spindle position without adapters or machining.
• Correct variant, matched by marking. The unit carries HUB=60 and D=28 KPL, and both markings are checked against your old spindle before packing.
• Two interchangeable part numbers. 2-031-95-4491 and 2031954491 are one spindle written in Homag's dashed and undashed formats, so either number on a purchase order reaches the same part.
• Vertical boring position. This is the drill spindle that holds and drives the bit in the vertical boring unit; horizontal drilling heads use a different spindle.
• HUB 60 mounting interface. The HUB=60 hub pilots the spindle in the head, so a spindle with another hub size sits proud of the seat and drills off position.
• D=28 bit bore. The D=28 KPL marking identifies the bit shank the spindle accepts, so the drill bit can be selected before the spindle ships.
• Machined metal body. The body is machined rather than pressed sheet, so the spindle survives being pulled and refitted during routine head service.
• Position held at the seat. Hole position comes from the spindle seating square in the head, and a matched hub keeps that seating identical across the row.

Faced with a worn drilling spindle, the real choice is not which brand to buy: it is whether to keep the head down, pay a service visit, or fit the correct part yourself.

• The head goes back into production the same day. A matched spindle is unbolted and refitted in the existing BHX 500 head, with no machining and no wait for a technician to travel.
• Fewer wrong-part shipments. Because HUB=60 and D=28 KPL are checked against your part number or a photo of the old unit, the return loop for a wrong hub size is avoided.
• One part number, two spellings. 2-031-95-4491 and 2031954491 both reach this spindle, so a work order written either way does not stall in purchasing.
• Cheaper than a lost shift. A stopped drilling head costs a shift of undrilled panels; one spindle costs a small fraction of that shift.
• Consistent hole pattern along the row. With every spindle in the drilling unit matched, the head drills the pattern the program expects instead of drifting on one unit.
• Spares consolidated in one shipment. Drill holders and other CNC machine parts can be ordered with the spindle, so one shipment covers a planned maintenance window.

Yes, it is listed for the Weeke BHX 500. The spindle is the vertical boring spindle for that head and carries Homag number 2031954491; still check the marking on the spindle you remove, because other Homag heads use a different spindle.

They are the two identifiers that pick the correct variant. HUB=60 is the hub marking that pilots the spindle in the drilling head, and D=28 KPL is the bore marking that identifies the bit shank it accepts.

Yes, both numbers point to the same spindle. 2-031-95-4491 is the dashed form written on the unit and 2031954491 the undashed form used in Homag parts lists and purchasing systems.

You can fit it yourself if you already service the drilling head. It is a bolt-in spindle that takes the factory position on the BHX 500, so no machining or adapter is involved; allow for re-checking hole position after the swap.

No separate fixture is sold with this part, the spindle is the holder. It carries the bit directly at the D=28 KPL bore, so the bit is held by the spindle itself, not by an extra attachment.

No, this listing is the spindle only. Drill bits and quick-change holders are separate items, and they can be ordered together with the spindle so the shipment covers the whole maintenance job.

Send a photo of the spindle and the machine model, and the marking is matched for you. Add the machine name Weeke BHX 500 and, if you have it, the parts-list number 2031954491, so the HUB=60 / D=28 KPL variant is confirmed before dispatch.

Send the quantity you need and you get a quotation, price is quoted per order rather than fixed on the page. State the part number 2-031-95-4491 and how many spindle positions you are replacing, so the quote covers the right quantity in one line.
