Drilling Machine Biesse Spare Parts Plastic Stopper For Six Row Drill

A six-row drill head references every hole off a stopper, so a worn or missing stopper is why one row of holes drifts while the other five stay true. This is the black plastic stopper used on Biesse six-row drill heads, also called a pusher in the machine parts list. It seats in the drill row and holds the workpiece reference during the stroke.

A drilling machine that has started producing one bad row is not a machine that has started drilling badly. The six rows reference off the same workpiece stop, and if the stopper at one position has worn, cracked or gone missing, that row indexes off a different face. The holes are still round and still clean; they are simply in the wrong place.

This is the replaceable stopper for that position on a Biesse drilling machine: black plastic, seated at the six-row drill head. It is listed as a stopper and as a pusher in the machine's parts terminology, which is why a search for either term should land on the same part.

Plastic is the right material here because the stopper contacts the workpiece directly and a harder material would mark it. The trade-off is that plastic wears and cracks at the fixing point, and that is exactly the failure that produces a drifting row rather than an obvious break.

The part carries no model number, so identification is by machine and by position: send a photo of the old stopper and the drill head it sits on, and it is matched against the Biesse six-row drill. Packing is a standard carton box, and vacuum suction cups for the same drilling machine are available from the same range.

What the part does at the drill head, and how to identify it:

• Six-row drill fit — seats at the six-row drill head on Biesse drilling machines and sets the workpiece reference for that row.
• Stopper and pusher — listed under both names in the machine's parts terminology, so either search term finds the same part.
• Black plastic — contacts the workpiece without marking it, which is the reason the part is not metal.
• Wear at the fixing point — plastic cracks at the fixing before it visibly breaks, which is what produces a drifting row.
• Position part, no model number — identified by machine and drill head rather than by a part number on the component.
• Standard carton box — packed for stock rather than for a single replacement.
• Matches the drilling machine range — vacuum suction cups for the same Biesse drilling machine are supplied from the same range.
• Small consumable — cheap enough to keep spares at the machine rather than ordering per failure.
• Reference for one row — each row indexes off its own stopper, so the part sets where that row's holes land relative to the panel edge.

What fixing the stopper actually restores:

• The drifting row lines up again. Five rows referencing correctly and one not is the signature of a worn stopper; replacing it puts that row back on the same reference as the others.
• No marks on the workpiece. Black plastic contacts the panel directly, so the stopper can hold the reference without leaving a print on the face.
• Cheap against a rejected batch. A worn stopper spoils the same hole position on every panel until it is changed, and the panels are already drilled by then.
• Identified without a part number. The component carries no model number, so a photo of the old stopper and the drill head is the practical way to match it.
• Stock at the machine. Small, cheap and quick to change, so spares belong at the drill head rather than in a store room.
• Same range as the suction cups. Vacuum cups for the same Biesse drilling machine come from the same supply, so one order covers both.
• One part, one row, one fix. The failure stays local: replacing the stopper at the drifting row restores that row without touching the other five.

Send a photo of the old stopper and the drill head it sits on, plus the machine model. The part is matched against the Biesse six-row drill rather than against a number on the component.

In the machine parts terminology for this part, yes: it is listed as both a stopper and a pusher for the six-row drill.

One row of holes drifts while the others stay true, or the workpiece no longer sits flat against the stop. Cracking at the fixing point is visible once the stopper is out.

Plastic, black. That is what allows it to contact the workpiece without marking it.

Standard carton box.

Yes. Vacuum suction cups for the Biesse CNC drilling machine are available from the same range.

One per position in use plus one spare is the usual practice, because a single worn stopper spoils every panel until it is replaced.
