H-12x46 Drill Holder Quick Change Chuck For CNC Drilling Machine

Changing a drill bit on a CNC drilling head without knocking the spindle out of setting is what the H-12X46 is for. It is a quick change chuck, a 12 x 46 mm drill holder listed for deep drilling, a wide drilling diameter range and an accurate drilling angle, with high accuracy, high durability, fast speed, low vibration and low noise on the sheet. Bits are released and re-clamped inside the chuck, so the holder stays on the spindle through the change. It is listed for wood, plastic and other materials in any workshop, and customization is available.

Three things go wrong on a drilling head that runs all day: a bit change that turns into a spindle reset, a holder that grips the bit in a way that lets it wander, and a chuck that has to be thrown away whole when one seat wears. The H-12X46 is built to remove all three.

The H-12X46 Drill Holder is a quick change chuck for CNC drilling machines and for woodworking boring work. The bit is released and re-clamped inside the chuck, so the drill holder stays on the spindle; the tool holder for drill bits and the chuck adapter are listed together for quick and easy fitting. Size code 12 x 46 mm.

On capability the sheet is specific: deep drilling depth, a wide drilling diameter range, an accurate drilling angle, high accuracy, high durability, fast speed, low vibration and low noise. Materials named are wood, plastic and other materials, for industrial and professional use and for any workshop.

The body is metal and listed as heavy, the mass a 12 x 46 mm holder needs at the end of a spindle turning at speed. Parts ship in a sealed protective box with bubble wrap, by air or freight depending on the size and weight of the order. Customization is listed as available.

What the H-12X46 changes at the spindle:

• Quick change, held in the chuck — the bit is released and re-clamped inside the holder, so the drill holder stays on the spindle through a size change.
• 12 x 46 mm on the part — size code H-12X46 is listed with the size, so the replacement is ordered against the head.
• Deep drilling depth — the sheet lists the holder for deep holes, the depth band where bit wander shows up first.
• Wide drilling diameter range — one holder is listed across a wide diameter band, so several bit sizes run from one chuck.
• Accurate drilling angle — listed as a holder property, and the one an operator loses first when a bit is knocked into a chuck by hand.
• Low vibration, low noise — both are listed, and vibration is what a heavy metal body of 12 x 46 mm is there to hold down.
• Metal body, heavy build — listed as metal construction and heavy weight, which is the mass that keeps a fast chuck stable at the spindle.
• Customization available — the sheet lists it as available, so a size other than 12 x 46 mm starts with a quote.
• Packed for the trip — sealed protective box and bubble wrap, then air or freight by order weight.

A drilling head that stops for every bit change is paid for twice: once in the hour, and again in the hole that drifts while the spindle is re-set.

• Change the bit, not the setting. The chuck re-clamps the bit in place while the drill holder stays on the spindle, so the setting dialled in for the run survives the change.
• One code covers the band. A 12 x 46 mm holder listed across a wide diameter range and a deep depth band means fewer part numbers and fewer wrong-size returns.
• The angle you keep is the angle you set. Drilling angle is listed as accurate, and it is the first thing lost when a bit is knocked into a chuck by hand.
• Quiet enough to live with. Low vibration and low noise are both listed, and vibration is what an oversize hole looks like before anyone measures it.
• Reorder by code, not by memory. Size is written as H-12X46 and 12 x 46 mm, so the second order and the tenth order are the same part.
• Non-standard sizes are quotable. Customization is listed as available, so a head that takes something other than 12 x 46 mm starts with a quote.
• Packed to arrive as it left. Sealed protective box and bubble wrap; air or freight chosen by order weight.

Yes, if your head takes a 12 x 46 mm drill holder. The sheet lists the part as a quick change chuck for CNC drilling machines and for woodworking boring work, with the tool holder for drill bits and the chuck adapter fitted for quick and easy installation; check the holder on your spindle against 12 x 46 mm before ordering.

It is 12 x 46 mm, listed under the code H-12X46. The sheet gives the size as H-12X46 and 12X46mm and nothing else, so the part is matched by that code rather than by a bore-and-length breakdown.

No. The bit is released and re-clamped inside the chuck, so the drill holder stays on the spindle; that is the whole point of a quick change chuck over a wrench-and-knock change.

Wood, plastic and other materials. That is the range the sheet names, alongside industrial and professional use and workshop use.

The sheet claims high accuracy together with an accurate drilling angle, and those two are the holder properties that decide whether the hole stays where it was marked.

Both are listed as held down: low noise and low vibration, on a metal body listed as heavy, which is the mass that steadies a fast chuck.

Yes. Customization is listed as available on this item, so a non-standard size starts with a quote rather than a dead end.
