PLA-168 Adjustable Drill Head For Woodworking Boring Machine Parts

Need a boring head that covers more than one hole pitch without buying a second head? The PLA-168 is an adjustable drill head for a woodworking boring machine: the wheelbase sets anywhere from 14 mm to 90 mm, a 76 mm band, and maximum drilling capacity is φ40 in wood and plastic steel. The body is steel alloys, listed as drilling machine spares. PLA-268 and PLA-368 are available in the same series. Price is by quotation, so send the model and the quantity.

A shop that bores dowel and shelf-pin holes hits the same three things: one fixed head per hole pitch, a second head bought the day the pitch changes, and a setup re-dialled every time the job changes over. The PLA-168 removes all three.

It is an adjustable drill head for a woodworking boring machine, listed as a drilling machine spare rather than a bench tool. The adjustable wheelbase runs from 14 mm to 90 mm, which is 76 mm of movement inside one head, so different hole spacing is set at the head instead of bought as another head. Maximum drilling capacity is φ40, rated for wood and plastic steel.

The body is steel alloys, so the drilling load passes through one material from the machine spindle to the bit. PLA-168 is the base code here; PLA-268 and PLA-368 are also available, so a workshop with more than one head size orders from 3 codes, not three suppliers.

Price is by quotation, so the model and the quantity are fixed before an order is raised. It is a replacement part: order against the head you are taking off and confirm the seat first. The buyer ends up with one head adjusted to the job in hand, not a shelf of heads set to pitches that have stopped running.

What the adjustable head changes at the boring machine:

• Adjustable wheelbase 14 mm to 90 mm — 76 mm of travel between the tightest and the widest setting, so dowel pitch and shelf-pin pitch are set on one head.
• φ40 maximum drilling capacity — the largest hole listed, rated for wood and plastic steel, so the figure has a stated application.
• Steel alloy body — the head is made from steel alloys, the material that carries the load between the machine spindle and the bit.
• One series, three codes — PLA-168, PLA-268 and PLA-368 are listed together, so the next head size up is 1 code away rather than a new supplier.
• A boring head, not a drill chuck — listed as a drilling machine spare, so it mounts where the old head came off.
• Pitch changed by setting — hole spacing follows the wheelbase, so a change of spacing is an adjustment at the head and not a change of head.
• Supplied as a spare part — a worn or knocked head is replaced as 1 part at the machine, with no rebuild on the bench.
• Quotation pricing — the price follows the model mix and the quantity, so a mixed 168 / 268 / 368 order is quoted as one list.

A fixed head and an adjustable head are close in price. The difference shows the next time the pitch changes: one head goes back on the shelf, the other stays on the machine.

• One head instead of a head per pitch. 14 mm to 90 mm of wheelbase covers a 76 mm band, so a change of spacing is a setting, not a purchase order.
• The big holes stay inside the range. φ40 is the top of the listed capacity in wood and plastic steel, so the heavy cuts do not need a second, larger head.
• A spare part, not a new machine. It is listed as a drilling machine spare, so a bent head is dealt with at 1 part and the boring machine keeps its place on the floor.
• Three codes, one order. PLA-168, PLA-268 and PLA-368 sit on the same page, so a shop with two head sizes keeps 1 supply line and 1 freight leg.
• Steel alloys where the load lands. The body is steel alloys, so the thrust from the bit runs through one material the whole way.
• Downtime counted in one part. A failure is a swap at the machine, not a strip-down, so the wait is 1 part instead of a rebuild.
• Quoted against your list. Price is by quotation, so a mixed order is quoted on the models and quantities you name.

A woodworking boring machine. It is listed as a machinery tool and as drilling machine spares for a woodworking boring machine, so it is a replacement head for that class of machine rather than a bench drill attachment.

14 mm to 90 mm, which is 76 mm of movement in one head. That band is what lets one head cover several hole pitches; the setting you need should be measured off the job, not guessed.

φ40. The sheet lists maximum drilling capacity as φ40 for wood and plastic steel, so that figure is the ceiling and it is tied to those two materials.

No. PLA-268 and PLA-368 are also available in the same series, so if the head you are replacing carries one of those codes, order that code and the wheelbase range still applies.

Steel alloys. The body material is listed as steel alloys, which is the part that carries the drilling load from the machine spindle to the bit.

No. Price is by quotation, so the number comes back against the model mix and the quantity you send, and a mixed 168 / 268 / 368 order is quoted as one list.

No. It is a spare head for a woodworking boring machine, so it mounts where an existing head mounts; it is not a standalone drilling unit with its own drive.

Match the head you are removing. Check the code on the old head and the wheelbase you run against 14 mm to 90 mm; send the old code or a photo and the fit is confirmed before the order is raised.
