As the 220V Fire Pipe Drilling Machine — φ16-φ114mm Holes, DN15-DN200 Pipe Compatible manufacturer, Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd builds the hole-cutting unit that sits between pipe cutting and pipe threading on a fire protection or plumbing installation. The machine runs on 220V AC 50Hz through a 750W motor, clamps onto DN15-DN200 pipe and cuts φ16-φ114mm openings with ±0.3mm positioning accuracy.
We have manufactured pipe fabrication and installation equipment in Hangzhou since 2010, and our drilling, threading, cold-cutting and pressure-testing products are used in fire protection engineering, construction engineering and municipal pipeline maintenance.
- Hole range: φ16-φ114mm, covering sprinkler drops, branch outlets and equipment tappings
- Pipe range: DN15-DN200, with a maximum pipe wall thickness of 8mm
- Accuracy: ±0.3mm hole positioning with a dedicated locator and clamping fixture
- Finish: smooth, burr-free hole edges that need no secondary reaming before fitting
One Machine for Branch Holes, Sprinkler Drops and Interface Tappings
Fire protection and plumbing crews drill the same kind of hole in three different places: a sprinkler head position on a branch line, a tee outlet on a riser, and an interface tapping where a pump, drain or chemical line connects. The 220V Fire Pipe Drilling Machine handles all three with one 220V single-phase drive, so it works from a standard site supply without a compressor, generator or three-phase connection.
The machine is built around a clamping fixture rather than a magnetic base. The pipe is gripped, the locator sets the hole centre, and the bit is fed into a wall of up to 8mm. That arrangement keeps the tool stable on round, galvanized and seamless pipe where a freehand drill would walk.

Because the fixture clamps the pipe rather than the bench, the machine can be used on prefabricated spools in a workshop and on installed lines in a plant room. That matters where a branch has to be added to an existing riser without dismantling the run.
Pipe Materials, Wall Thickness and Cutting Behaviour
- Galvanized steel pipe — the most common fire protection material; the bit set is matched to the coating and wall thickness.
- Seamless steel pipe — used for higher-pressure fire mains and pump connections; hole edges come out clean enough for direct fitting.
- PVC pipe — drain and wastewater work; the same locator and clamp set is used with a lower feed force.
- Wall limit — 8mm maximum. Stainless steel, thick-wall or lined pipe is reviewed against the working point before we confirm a configuration.
Hole quality is the reason crews use a dedicated machine instead of a hand drill. A burr-free edge means the outlet can go straight to threading, grooving or fitting without a reaming step, and the ±0.3mm position keeps outlet spacing consistent along a long run.
Clamping, Locating and Setup Sequence
Setup follows a fixed sequence so that two operators produce the same hole position on the same drawing. The clamping device grips the pipe, the locator marks the centre, the bit is mounted, and the feed is applied until the wall is pierced.
- Mark the hole centre from the spool drawing and seat the clamping device on the pipe.
- Fit the locator and confirm the centre line is square to the pipe axis.
- Install the drill bit for the required outlet size and tighten with the supplied hex wrench.
- Feed steadily; if the bit meets a hard section, the overload protection stops the drive.
- Release the clamp, clear swarf and check the edge before the fitting is offered up.
Overload Protection and Operator Safety
The built-in overload circuit stops the tool when the bit encounters a hard pipe wall or an obstruction. On site this prevents the reaction torque that a stalled bit transfers to the operator's wrists, and it protects the motor from a sustained locked-rotor condition.
The 220V single-phase supply keeps the machine inside the same power envelope as other site tools, and the clamping fixture holds the workpiece so both hands stay on the feed. We confirm the supply arrangement and the working position with the project team when a machine is specified for a fixed fabrication bay.
Configuration and Accessories We Supply
Each machine ships with a drill bit set, locator, clamping device and hex wrench, so the first hole can be cut without a separate tooling order. Beyond that base package, the configuration is set by the outlet schedule and the pipe band the project actually uses.
- Bit set coverage — the φ16-φ114mm range is supplied as a set; individual sizes can be specified where a project repeats one outlet dimension.
- Clamp and locator sizing — matched to the DN15-DN200 band, with the working diameters confirmed from the pipe schedule.
- Voltage and frequency — the standard build is 220V AC 50Hz; supply conditions outside that are reviewed before quotation.
- Spare bit and fixture supply — consumable and fixture items are available as separate line items for crews running continuous production.
Where the Machine Sits in Our Pipe Fabrication Range
Hole cutting is one step in a sequence. Our pipe fabrication and installation equipment range covers the steps around it, and we configure the set around the spool drawings a project actually issues.
Information We Use to Configure Your Solution
A quotation is built from the pipe schedule and the outlet list, not from a catalogue number alone. The details below let us confirm the bit set, fixture sizing and supply arrangement in one pass.
- Pipe material, nominal diameter and wall thickness for every line in scope
- Outlet sizes required, with the count of each diameter per spool or per project
- Site supply voltage and frequency, and whether work is in a fabrication bay or on installed lines
- Hole position tolerance and any drawing dimension that governs outlet spacing
- Whether the outlet is threaded, grooved or welded after drilling, so edge finish is matched to the next step
- Quantity of machines, spare bit and fixture requirements, and operator training needed at handover
Quality Control, Documentation and Support
Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd operates a 10,000m² factory with more than 100 employees and holds the title of National High-tech Enterprise, with 30 patents covering pipe threading, clamping and tooling design. Our nine generations of intelligent threading machines were developed in-house, and the same engineering and assembly discipline applies to the drilling range.
Our conformity documentation includes a Machinery Directive and Electromagnetic Compatibility Directive attestation of conformity. Machines are checked at assembly and before packing, and the shipment includes the standard accessory set together with the operating documentation for the model supplied.
Our technical team provides demonstrations and operator training on the machines we supply, and spare parts for the drilling and threading ranges are held as service items so that a worn bit or fixture does not idle a fabrication bay.
Frequently Asked Questions
What pipe sizes and hole diameters does this machine cover?
The machine cuts φ16-φ114mm holes in pipe from DN15 to DN200, with a maximum pipe wall thickness of 8mm. Hole positioning accuracy is ±0.3mm when the supplied locator and clamping device are used as intended.
Which pipe materials is it specified for?
The standard specification covers galvanized steel pipe, seamless steel pipe and PVC pipe. Stainless steel, thick-wall or lined pipe falls outside the standard 8mm wall limit and is reviewed against the working point before we confirm a configuration.
How is the hole kept at ±0.3mm?
The clamping device grips the pipe and the locator sets the hole centre square to the pipe axis before the bit is mounted. Because the workpiece is held rather than the tool being guided freehand, the position repeats from spool to spool and from operator to operator.
What happens if the bit hits a hard section of pipe wall?
Built-in overload protection stops the tool when it meets a hard wall or an obstruction. This limits the reaction torque reaching the operator and prevents the 750W motor from running in a locked condition.
What is included with the machine, and what power supply does it need?
The standard package contains the drill bit set, locator, clamping device and hex wrench. The machine runs on 220V AC 50Hz single-phase supply with a 750W motor; projects with a different supply voltage or frequency are reviewed before the order is confirmed.
