Hinge Boring System With 21 Spindle Head Woodworking CNC Machining Parts 32x21

Need to bore a full row of hinge, dowel or shelf-pin holes in one pass? This boring head carries 21 spindles in a single housing, so a woodworking drilling machine drills a complete hole row in 1 stroke. Spacing is set by the head, so every panel gets the same pitch without re-marking. Body is hardened steel, drill bits are interchangeable, and the part is ordered as size code 32x21 with the 21-spindle configuration. Price is quoted per order, shipped from China by DHL, FedEx or UPS.

A hinge boring system with 21 spindles is one drilling head that bores a complete row of hinge, dowel or shelf-pin holes in a single stroke on a woodworking drilling machine. Shops fitting cabinets usually run into the same three things: a single-spindle drill and a pencil for every panel, hole positions re-measured at each setup, and pitch that drifts from one operator to the next.

This head answers all three from the housing. All 21 spindles sit in one body, so the space between drill bits is set by the part, not by the operator: 21 holes per pass, the same pitch on the next panel, and no re-calibration between cabinets. Bits are interchangeable, so a different hole diameter does not mean a different head. The 32x21 in the product name is the size code; quote 32x21 together with the 21-spindle configuration when you order.

The body is built from hardened steel for continuous production, with alignment held across the full row of spindles so the line of holes stays on one centre line. It is a boring head for a woodworking drilling machine, not a stand-alone bench drill. Shipment runs from China by DHL, FedEx or UPS, and price is quoted per order.

What separates this head from a single-spindle setup sits in the housing and the spindle row, not in the paint.

• 21 spindles, one housing — all 21 bits run in one casting, so a full row is 1 stroke at 1 position instead of 21.
• Pitch fixed by the part — the spacing between bits is machined into the housing, so the pitch does not change from the first panel to the last.
• Hinge, dowel and shelf-pin work — used as a boring head on woodworking drilling machines for hinge mounts, dowel joints and shelf-pin rows.
• Interchangeable bits — swap drill bit sizes without changing the head, so 1 head covers several hole diameters.
• Hardened steel body — high-strength hardened steel construction, specified for continuous industrial woodworking production rather than occasional use.
• Alignment across the row — the 21 spindles are aligned to one centre line, which is what keeps the drilled line straight and equally spaced.
• 32x21 size code — the head is ordered by 32x21 plus the 21-spindle configuration; quote both numbers to avoid receiving a different size.
• One-pass cycle time — repetitive drilling collapses to a single pass per panel, which is where cabinet line time is actually spent.
• Replacement part, not a rebuild — catalogued as a woodworking machine part, so a worn or out-of-line head is swapped without touching the drilling machine.

The usual choice is a cheap single-spindle drill and a second machine for line boring, or sending panels out. This head answers both on the drilling machine already on the floor.

• One pass replaces 21 strokes. A shelf-pin row is 21 holes: a single-spindle drill needs 21 positions and 21 strokes, this head needs 1 of each.
• The same row on second shift. Pitch lives in the housing, so the late shift produces the 21-hole pattern the morning shift produced, with no re-marking and no drift.
• One head, several hole sizes. Because the bits are interchangeable, hinge, dowel and shelf-pin holes can run off one head instead of one head per diameter.
• Built for a production line. A hardened steel body and full-row alignment matter where a head that wanders costs panels, not minutes.
• A drop-in spare, not a retrofit. It is catalogued as a woodworking machine part with a 32x21 size code, so a worn boring head comes off and a new one goes on.
• Quoted per order, shipped 3 ways. Price follows the quantity you ask for, and delivery runs by DHL, FedEx or UPS from China, one replacement head or a full batch.

21 holes. All 21 spindles sit in one housing, so the full row is drilled in a single stroke at a single position, with no indexing from hole to hole.

It is the size code of this head. Quote 32x21 together with the 21-spindle configuration when you ask for a price, so the quote matches the boring head you need.

It fits as a boring head on a woodworking drilling machine. The part is supplied as a boring head and drill head for that machine type, so compare the mounting on your existing head before ordering.

No. The drill bits are interchangeable, so one head covers several hole diameters: you change the bits, not the head.

Yes. Spacing is held by the housing, and the full row of spindles is aligned to one centre line, so the pattern repeats panel after panel without re-calibration.

It is a spare part, a boring head, not a machine. It mounts on a woodworking drilling machine and is catalogued under woodworking machine parts.

Hardened steel. The body is built from high-strength hardened steel for continuous production lines, with the 21 spindles aligned to a common centre line.
