Engineering Construction Pipeline Connection Solutions

Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd manufactures cordless power tools and intelligent pipe connection equipment for engineering construction. Our Brushless Circular Saw manufacturer programme covers handheld cordless cutting of wood, panels, plastics, metal sheet and pipe directly at the work face, running on the same 21V lithium-ion platform as the rest of our cordless range.

Established in 2010, we hold the National High-Tech Enterprise title and more than 30 patents covering threading, clamping and pipe connection mechanisms. The cordless range came out of the same engineering team: tools that are carried to the installation point, run without a trailing cable, and produce a cut clean enough that the joint can be assembled without rework.

Engineering Construction Pipeline Connection Solutions: Where Cordless Cutting Fits

The cordless tools support our Engineering Construction Pipeline Connection Solutions programme, which covers the sequence from pipe pretreatment to precise connection: variable frequency cold saw cutting, intelligent threading, and intelligent pipe tightening. On a fire protection or building installation project, the circular saw handles trim, support and panel work while the fixed machines produce the threaded and cold-cut pipe runs.

Because the whole range shares one battery platform, a crew carries one charger set and one spare-parts list across cutting, drilling, bolting and punching tasks. That matters on refurbishment and fit-out work where power drops are scarce and the work face moves floor by floor.

Our Cordless Range and the Task Each Tool Covers

XJ.853 21V High-Magnetic Brushless Circular Saw

The XJ.853 is our industrial-grade handheld circular saw for straight cuts in wood, panels, plastics and comparable sheet materials. A high-magnetic brushless motor drives a 140 mm blade, and the laser guide line lets the operator follow a marked line without clamping a straight edge for every cut.

Materials, Blade Selection and Cut Quality

Cut quality on a cordless saw is decided by blade choice, material support and feed rate rather than by motor size alone. We match the blade to the workpiece and confirm the tooth geometry and kerf with the customer before shipment, because the same saw is used on softwood formwork in one week and on aluminium trim in the next.

• Wood and panels: coarse-tooth blades clear chips quickly and keep the cut line straight on plywood, MDF and board stock.
• Plastics: fine-tooth blades reduce chipping and heat build-up on PVC and similar sheet.
• Metal sheet and thin-wall pipe: dedicated metal-cutting blades with controlled feed; heavy-wall steel pipe is better handled on our Variable Frequency Cold Saw for burr-free, cool cuts.
• Support: material should be supported on both sides of the cut so the offcut does not pinch the blade.

Battery Platform, Runtime and Site Logistics

All cordless tools in our range run on the 21V lithium-ion platform, so packs, chargers and spares are interchangeable across cutting, drilling, punching and bolting tasks. For high-draw work such as sustained circular saw cutting or rotary hammer drilling overhead, the backpack battery pack moves the weight off the tool and onto a harness, which extends usable runtime and reduces wrist load.

We confirm the pack and charger quantity against the shift pattern, the number of operators and whether charging happens on site or in a site cabin. Tools are supplied with the accessories needed to start work, and the packing list is agreed before dispatch.

Safety, Controls and Line Integration

The brushless circular saw is a handheld tool, so its safety design centres on blade guarding, kickback control and operator grip. The anti-kickback guard, overload protection and anti-slip handle are standard on the XJ.853, and the 0–45° bevel is set with a positive stop rather than by eye.

Where the saw feeds a fixed production line rather than a handheld operation, we discuss the interface separately: cut length, cycle time, infeed and outfeed support, and how the operator confirms the cut before the pipe moves to threading or tightening. Our wider equipment range — including the Pipe Fabrication & Installation Equipment group — is configured around that workflow so the handheld and fixed stages use consistent cut and thread references.

Quality Control, Acceptance and Compliance

Tools are assembled and function-tested before packing, with motor, switch, guard, bevel adjustment and laser guide checked as part of the routine. Our certification file includes an Attestation of Conformity referencing the Machinery Directive and the Electromagnetic Compatibility Directive, and the company holds the National High-Tech Enterprise title with more than 30 patents in pipe connection and threading mechanisms.

• Incoming inspection of motors, switches, guards and battery interfaces
• Assembly checks on blade alignment, bevel scale and guard return
• Function run and laser guide verification before packing
• Documentation set issued with the shipment for project acceptance files

Information We Use to Configure Your Solution

A quotation is prepared from the working point, not from a catalogue number alone. The details below let us fix the blade, battery configuration, accessory set and packing scope in one pass.

• Material and thickness to be cut, plus whether metal sheet or pipe is included
• Required cut depth and whether bevel cuts are needed
• Cut length range and the number of cuts per shift
• Site power availability and charging arrangements
• Battery and charger quantities, including backpack pack requirements
• Market voltage, plug type and language for labels and manuals
• Quantity, delivery destination and required documentation

Maintenance, Spare Parts and Documentation

Brushless motors remove the carbon-brush service item, so routine maintenance focuses on blades, guards, the bevel mechanism, battery contacts and ventilation paths. We supply spare parts across the cordless range and provide operator and maintenance training for buyer partners on request, covering blade changes, guard checks and battery handling.

Each shipment carries the operating manual, packing list and the conformity documentation needed for the project file. For distributors, we align carton marking, spare-parts kits and consumable lists with the way the tools will be resold or deployed.

Frequently Asked Questions

What is the maximum cutting depth of the XJ.853 brushless circular saw?

The XJ.853 runs a 140 mm blade with a maximum cutting depth of 45 mm at 90°. When the base is set to a bevel angle between 0° and 45°, the effective depth of cut reduces accordingly, as with any circular saw.

Can your brushless circular saw cut metal pipe?

It cuts metal sheet and thin-wall pipe with a suitable metal-cutting blade and a controlled feed rate. For heavy-wall steel pipe where a cool, burr-free cut and a square end face are required before threading, we recommend our variable frequency cold saw, which is built for that operation.

Which battery platform do the cordless tools use?

Our cordless range runs on a 21V lithium-ion platform, so packs and chargers are shared across the circular saw, angle grinder, hammer drill, rotary hammer, wrench, hole puncher and spray gun. For extended runtime on high-draw tools, the backpack lithium battery pack carries the pack on a harness.

How do you handle spare parts and training?

We supply spare parts for the cordless range and provide technical support and training for buyer partners on request, covering operation, blade and guard maintenance, and battery handling. Training scope and timing are agreed with the order.

What documentation comes with a shipment?

Shipments include the operating manual, packing list and the conformity documentation held for our equipment, including the Attestation of Conformity referencing the Machinery Directive and the Electromagnetic Compatibility Directive. Additional project-file documents are agreed at order stage.

Do you supply the full pipeline connection sequence as well as cordless tools?

Yes. Alongside the Cordless Power Tools range we manufacture intelligent threading machines, intelligent pipe tightening machines, cold saws, fire pipe drilling machines and pressure test pumps, covering pipe pretreatment through to final connection.
