Hydraulic Vertical Drilling Base For Horizontal Woodworking Drilling Machine Spare Parts

Rebuilding the vertical drilling station on a horizontal woodworking drill? The HT260520B hydraulic vertical drilling base is the steel transmission unit that holds the drilling spindle and carries the hydraulic feed into the cut. It is a replacement spare part for horizontal drilling machines, not a new machine and not a spindle assembly. Material steel, origin China, lead time 7–15 working days. No drawing dimensions are published, so the fit is confirmed from the old base and a photo of the spindle end before the order is placed.

A horizontal drilling machine that drills off position usually has nothing wrong with the spindle. Three things fail upstream: the vertical base works loose in its clamp and the head drops a few tenths, the hydraulic movement turns sticky so the feed hesitates mid-panel, and the base leaves the machine for a repair that should have been a swap. The HT260520B answers all three from one mounting position.

The HT260520B is a hydraulic vertical drilling base for horizontal woodworking drilling machines, classified as a transmission mechanical part. Material is steel; origin is China. As photographed, it is a vertical housing with a flat-sided mounting stem and a ground spindle through it, plus one grease point on the body. It is machine structure, not a wear surface.

The hydraulic side explains the weight. Force is transferred by hydraulic pressure across the full stroke rather than by a lever that flexes, so the drilling components hold position between cycles and vibration at the cutting point drops. That is the difference between the first hole in a batch and the four hundredth.

Lead time is 7–15 working days from China; price is quoted per order. No drawing dimensions are published for this part number, so fit is confirmed from the old base: stem section, spindle end and grease point location.

What the part number covers, and what decides whether it mounts:

• Steel body — material is stated as steel, so the load path from the drilling spindle into the machine frame stays metal end to end.
• Hydraulic duty — listed as a hydraulic transmission component for horizontal drilling machines; the feed it carries comes from hydraulic pressure, not a hand lever.
• Vertical base, horizontal spindle — the spindle leaves the housing horizontally, which is what puts the drill at panel height on a horizontal machine.
• Flat-sided mounting stem — the stem clamps into the machine station and indexes on a machined slot, as photographed, so the base can only sit in one orientation.
• Grease point on the body — one nipple on the housing, reachable with the base bolted in place, so lubrication does not need a teardown.
• Vibration control — the hydraulic movement is listed for reduced vibration and stable positioning of the drilling components between cycles.
• Replacement, not rebuild — sold as a spare part for maintenance, replacement and equipment upgrades on existing furniture and panel processing lines.
• Part-number ordering — HT260520B is a part number, so the order is matched to the number on your old unit instead of to a written description.
• Short lead time — 7–15 working days from China, quoted together with the price for the quantity you need.

Two bad options when the drilling station drifts out of position: send the head out, or keep running and let scrap tell you when to stop. The base is the third.

• A swap instead of a rebuild. The part number replaces the base on an existing horizontal drilling machine, so the station drills again without a machine-level rebuild.
• The spindle keeps its position. Hydraulic transfer across the full stroke and reduced vibration leave the drilling components where they were set, so hole spacing repeats panel to panel.
• Steel where the load is. The base is steel — the material that has to hold clamp preload on the stem every shift instead of taking a set.
• Maintenance without removal. The grease point sits on the body and stays reachable with the base in place, so lubrication is a routine stop, not a strip-down.
• Downtime you can plan. A 7–15 working day lead time is short enough to order against a scheduled maintenance window rather than a stopped line.
• Fit checked before shipping. Send the stem section, the spindle end and a photo of the old unit, and the base is compared with your station before it ships.
• One line on the purchase order. HT260520B identifies the part, so the second and third stations on the same line can be ordered by number instead of by description.

Check it against the old base before ordering. No drawing dimensions are published for this part number, so the reliable test is the unit that comes off your machine: stem section, spindle end and the position of the grease point. Send those with a photo and the base is compared for you.

Just the base assembly shown in the product photos. The images for HT260520B show the vertical housing, the spindle through it, the flat-sided stem and one grease point; hydraulic lines and machine-side fittings are not part of what is photographed.

Steel. The product data lists steel as the material and China as origin, so the clamp stem and housing are metal, not a cast polymer substitute.

Both, in the way the listing uses the words. It is described as a hydraulic vertical drilling base and classified under transmission mechanical parts for horizontal drilling machines.

7–15 working days. That is the stated lead time from China; the exact dispatch date is confirmed with the quotation.

Price is quoted per order rather than published. Send the quantity you need per station and the quotation comes back with the price and the lead time together.

Horizontal woodworking drilling machines. The applications listed are furniture manufacturing and cabinet and panel processing lines, including maintenance, spare part replacement and equipment upgrades.

It mounts at the existing station. The stem clamps into the same position and the spindle leaves horizontally, so the base returns where the old one came from; drilling depth and position still need checking on the first panel.
