21 Spindles Boring Head 32x21 Drill Bits Connector Spares For Drilling Machine

The 21 Spindles Boring Head from Shunhongyu is a woodworking drilling machine part that carries 21 spindles and connects to 32x21 drill bits, enabling multi-hole line boring in one pass. It fits drilling machines that accept a 21-spindle head and 32x21 bit connectors. Before ordering, confirm your machine's spindle count, bit connector size, and mounting pattern match. The head is built for alignment and repeated use, and ships by DHL, FedEx, or UPS from China.

When a line boring head drifts, shelf pin holes and dowel joints no longer line up, and the fix usually means re-clamping and re-drilling. A head with 21 spindles and 32x21 bit connectors keeps the drill bits in a fixed pattern so all holes in a row are drilled in one pass.

This is a 21 Spindles Boring Head made by Shunhongyu for woodworking drilling machines. It uses 32x21 drill bit connectors and is classed as a woodworking machine spare part. To confirm fit, check that your machine takes a 21-spindle boring head and that its bit holders match the 32x21 connector.

Mounting the head means aligning it to the machine's spindle drive and locking it in place so the 21 spindles sit square to the table. With the 32x21 connectors fitted, each bit runs in its set position across the row. In use, that fixed spacing is what lets you drill repetitive hole patterns without measuring each hole.

Supply runs from China, with shipment by DHL, FedEx, UPS, or similar. No packing, customisation, MOQ, or lead time terms are stated here. When you enquire, send your machine make and model, the spindle count you need, the bit connector size, and a photo of the current head's mounting face. That lets the supplier check the 21-spindle head and 32x21 connector against your machine before you commit.

What the specification fixes, and what it leaves to the machine:

• Spindle count for row drilling — 21 spindles hold the drill bits in one row so you can bore multiple holes in a single machine pass.
• Bit connector size — The head takes 32x21 drill bits connectors, so check your existing bit holders match this connector before ordering.
• Alignment of the drill row — With 21 spindles fixed in position, the drill bits stay aligned to each other for evenly spaced holes.
• Construction for repeated use — Built for durable construction, the head is intended to hold up under the repeated cycles of woodworking drilling.
• Machine fit check — Designed as a boring head for woodworking drilling machines, it suits machines that accept a 21-spindle head.
• Spare-part role — As a woodworking machine spare part, it replaces the boring head on your drilling machine when the old one is worn.
• Mounting face — The head mounts to the machine's spindle drive; confirm the mounting pattern matches your machine before fitting.
• Bit retention points — Each of the 21 spindles carries a 32x21 connector, so check every connector seat for wear when you service the head.
• Brand and origin — Shunhongyu brand, made in China, this 21 Spindles Boring Head is supplied as a complete drilling head assembly.

What changes on the shop floor when the right part goes back in:

• One pass instead of many. With 21 spindles working at once, a row of shelf pin or dowel holes is drilled in a single pass, cutting the repositioning that causes misalignment.
• Hole spacing stays fixed. The 21-spindle layout keeps the drill bits at set spacing, so repeated rows match each other without re-measuring every hole on the machine.
• Fit checked before you buy. Because the head uses 32x21 drill bits connectors, you can compare your bit holders and spindle count to the head and avoid a wrong order.
• Built for continuous drilling. Durable construction suits the repeated cycles of cabinet and furniture drilling, where the head runs row after row through the shift.
• A direct spare-part swap. As a woodworking machine spare part, it replaces a worn boring head on a drilling machine that takes a 21-spindle head.
• Alignment you can set once. High precision alignment means the drill bits stay in line after mounting, so you spend less time adjusting the head between jobs.
• Courier choice from China. Shipment by DHL, FedEx, or UPS lets you pick the carrier and track the head to your door.

Check your machine takes a 21-spindle head and uses 32x21 drill bits connectors. Compare the spindle count, connector size, and mounting pattern with your current head before ordering.

It uses 32x21 drill bits connectors. Confirm your bit holders match that connector size, because the 21 spindles are set up for 32x21 bits.

It drills a row of holes in one pass with 21 spindles. That suits shelf pin holes, dowel joints, and hinge mounts where the holes must line up.

It is a boring head for woodworking drilling machines. It is classed as a woodworking machine spare part and is not intended for other machine types.

It mounts to the machine's spindle drive and locks so the 21 spindles sit square to the table. Align the head before tightening, then fit the 32x21 connectors.

Send your machine make and model, the spindle count, the bit connector size, and a photo of the current head's mounting face. That lets the supplier check fit.

Shipment is by DHL, FedEx, UPS, or similar carriers from China. No packing, MOQ, or lead time terms are stated, so ask the supplier for those details.
