China Professional Electric Cutting Tools Manufacturer

BOSI Tools is an electric cutting tools supplier from China, offering the Stone Cutting Machine, Profile Cutting Machine, and Engineering Cutting Machine.

From tiles and stone to heavy-duty steel sections, the core of a cutter lies in the integrated matching of power, base plate precision, and protective design—BOSI combines a power range of 1400W to 3 kW with an aluminum gear housing and a quick-clamping system to make cutting different materials more precise and efficient. We respond promptly to both standard selections and special customizations, and inquiries are welcome.

Working Principle

The working principle of BOSI electric cutting tools varies in emphasis depending on the model positioning, but their common feature is that a motor drives a saw blade to rotate at high speed, completing the cut through circular cutting action.

The Stone Cutting Machine uses a 1400W pure copper motor to drive a 110mm diamond blade. Its ultra-high speed of 14,200 r/min works together with a thickened base plate that can be adjusted from 0° to 45°, cutting through tiles and stone by high-speed grinding. Water cooling is required during cutting to reduce dust and prevent the blade from overheating.

The Profile Cutting Machine uses a high-power 2450W/2500W motor to drive a 355mm resin-bonded abrasive cutting disc. A 3800W overload capacity ensures no slowdown or stalling when cutting solid metals such as angle iron and round steel. A semi-enclosed protective guard design combined with a spark shield directs the spray of sparks toward the rear and downward. A quick-clamping system locks the workpiece onto a thickened, heavy-duty base plate, and a cutting depth limiter device prevents the base plate from being damaged by cutting through the bottom.

The Engineering Cutting Machine uses a 3 kW pure copper industrial motor to drive a large 400mm-diameter saw blade. 380V three-phase power ensures a stable 2,880 r/min output, and the reinforced welded base and overall machine rigidity ensure the precision and safety required for heavy-duty cutting.

Our Cutter Products vs. Other Brands: Why Choose BOSI?

BOSI cutters bring together core configurations including an aluminum gear housing, overload capacity, quick-clamping, and safety protection, and through rational pricing, allow small and medium processing factories and construction sites to obtain near-professional-grade cutting precision and safety assurance.

How to Choose the Right Cutter?

When choosing, prioritize the cutting object:

For ceramic tiles and stone, you must choose a Stone Cutting Machine. Its 110mm blade is used with water cooling, and the 0°-45° adjustable base plate handles bevel cuts.

For metal cutting, select according to the steel specification—a 2500W Profile Cutting Machine is sufficient for angle iron and standard round steel, with the quick-clamping and spark shield ensuring efficiency and safety.

For batch cutting of large-sized, thick-walled steel or rails, the 3 kW Engineering Cutting Machine is essential, with 380V power ensuring no speed drop under continuous heavy loads.

Of the two Profile Cutting Machine models, the 2500W version adds a D-type extra-long handle, a cutting depth limiter device, and an external carbon brush protective cover, offering superior operating comfort and maintenance convenience.

Common Problems During Operation and Solutions

Safety Precautions for Use

1. Personal Protective Equipment

Safety goggles or a face shield, a dust mask, earplugs, and flame-resistant work clothes must be worn when operating a cutter.

Metal cutting produces high-temperature flying sparks; wearing synthetic fiber clothing is strictly prohibited. It is recommended to also wear a leather apron and cut-resistant gloves.

2. Blade Inspection

Before use, confirm that the abrasive disc or diamond blade is free of cracks, dampness, and deformation, and that its rated speed is higher than the tool's no-load speed.

During installation, a soft spacer must be placed between the flange and the disc, and the securing nut should be tightened moderately, not excessively.

For the Stone Cutting Machine, confirm that the diamond blade’s bore size matches and that it is mounted in the direction of the arrow.

3. Workpiece Clamping

Before cutting, lock the workpiece using the quick-clamping system. Hand-holding the workpiece while cutting is strictly prohibited.

The Profile Cutting Machine’s thickened, heavy-duty base plate ensures the machine body is stable and adequately supported; the Engineering Cutting Machine’s reinforced welded base meets the stability requirements for heavy loads.

4. Operating Posture

Operate with one hand on the handle applying light pressure (the Profile model’s D-type extra-long handle can be held with both hands), and slow down the feed rate during cutting. Keep your body out of the plane of the abrasive disc.

The semi-enclosed protective guard design and spark shield direct sparks downward, but the operator must still maintain a safe distance from the spark trajectory. The cutting depth limiter device can preset the stroke to prevent the cut from hitting the bottom and damaging the base plate and abrasive disc.

5. Environment & Power Supply

For 220V models, ensure proper grounding. For the 380V Engineering model, confirm the three-phase wiring is correct and that it is equipped with an independent circuit breaker.

In wet environments, always use a leakage protector. Clear the work area of flammable materials, and maintain a safety radius of no less than 2 meters.

6. Maintenance and Care

Only remove offcuts or change the blade after the abrasive disc has come to a complete stop.

Regularly clean the inside of the guard and the base plate of accumulated debris, and check the carbon brush length.

The 2500W model’s external carbon brush protective cover allows for labor-saving replacement without disassembling the machine. For the Engineering model, periodically inspect the structural integrity of the welded base and store it in a dry, ventilated place.
