Biesse Drilling Machine Spare Parts Plastic Stopper For Six Row Drill

Need the stopper that sets the reference face for one row of a Biesse six-row drill head? This is it: a black plastic block, listed as a stopper and as a pusher, fixed through 1 through hole at 1 of the 6 drill rows. No model number is moulded into the part, so it is matched by photo plus item 46695791. Packing is a standard carton box, origin China, price by quotation, and vacuum suction cups for the same Biesse CNC drilling machine come from the same range.

One row out of position on a six-row head is usually a stopper, not a loss of accuracy. Every row references off its own stopper, so a cracked or missing block at 1 position makes that row index off a different face while the other 5 stay true. The holes stay clean; they are simply in the wrong place.

This is that block: the black plastic stopper for the six-row drill head on Biesse drilling machines, listed as a stopper and as a pusher. It seats at 1 of the 6 rows, sets that row's reference face, and bolts through the 1 through hole moulded into the body.

Plastic rather than metal is the practical choice here: the face that touches the panel is not steel. The trade-off sits at the fixing point, where plastic cracks first, and a cracked stopper still looks whole while bolted on. That is why the fault shows as a drifting row, not a broken part.

No model number is moulded into the component, so identification runs on position and photo: the drill head, the row, and item 46695791 on this listing. Packing is a standard carton box, origin China, price by quotation. Vacuum suction cups for the same Biesse CNC drilling machine ship from the same range, so 1 order covers both.

What the part does at the drill head, and how it is identified:

• Six-row drill fit — seats at 1 position on the six-row drill head of a Biesse drilling machine and sets the reference face that row drills from.
• Stopper and pusher — the same block is listed under both names in the parts terminology, so either term identifies 1 part on the machine.
• One through hole — the body carries 1 moulded through hole for the fixing screw, so the block is held from the face rather than clamped from the side.
• Slot-located body — the stepped body and its slot fix the seating direction, leaving 1 way to fit it in the row.
• Black plastic body — plastic at the contact face and black all through, so a worn face reads as a lighter polished patch against the otherwise matte block.
• Wear point at the fixing — plastic cracks at the fixing hole before the body fails, and that crack is what lets the row's reference face move.
• Standard carton box — packed in a standard carton box and shipped from China, with no special packing needed for a small spare.
• Same range as the cups — vacuum suction cups for the same Biesse CNC drilling machine are supplied from the same range, so 1 order can cover cups and stoppers.

What replacing one stopper actually restores:

• The row lines up again. When 5 rows hit and 1 drifts, the cause sits at the drifting row's stopper; changing that block puts the row back on the same reference as the other 5.
• One block, not a head group. The replacement is 1 plastic block, so the drill head stays on the machine while it is swapped.
• Rejected panels stop repeating. A worn stopper repeats the same error on every panel until it is changed, and the panels are already drilled by then; 1 spare block at the machine ends that loop.
• Ordering without a part number. A photo of the old block, the drill head it sits on and item 46695791 is enough to match it, which is the practical route when the component carries no number.
• Fitted at the machine. 1 through hole and 1 seating direction: no setting-up, no measuring of the reference face beyond bolting the block back down.
• Spares that fit the drawer. A small plastic block in a standard carton box is cheap to hold, so 2 or 3 can sit at the machine instead of one being ordered per failure.
• One order, two part families. Vacuum suction cups for the same Biesse CNC drilling machine come from the same range, so cups and stoppers travel together.

Send a photo of the old block and the drill head it sits on, plus the machine model and the row it comes from. Add our item number 46695791 and it is matched against the Biesse six-row drill rather than against a number on the component.

Yes, on this part the two names mean the same block. It is listed as a stopper and as a pusher for the six-row drill, so either term brings you to the same item.

The drilled row drifts while the other rows stay true. Take the block out and look at the fixing hole: plastic cracks there before the body breaks, and the crack is what lets the reference face move.

Black plastic. Body and contact face are both plastic, and colour is black.

One per row in use, plus one spare. A six-row head uses 6 in service, and a single cracked block spoils every panel until it is replaced.

Standard carton box, shipped from China. Nothing special is needed for a part of this size.

Yes. Vacuum suction cups for the same Biesse CNC drilling machine are available from the same range, so cups and stoppers can go in one order.

Price is by quotation. Send the quantity, the machine model and a photo of the old part, and the quotation follows from there.
