01SAW ACCESSORIES
Precision circular cuts in wood and metal
A precise instrument for creating clean, circular openings in diverse materials, this tool transforms a standard drill into a dedicated cutter. Its black finish suggests robustness, while the geometry promises accuracy in every rotation.
Designed for tradespeople and DIY enthusiasts, it handles gypsum board, plywood, plastic and thin metals with stability. The integrated hardware ensures the bit stays true to the workpiece, delivering consistent results without excessive vibration.


02MATERIALS
Bimetal alloy for durability
Crafted from M42 bimetal, the blade combines high hardness with significant toughness. This composition provides impact resistance and wear resistance, allowing the edges to remain sharp through repeated use. The material also exhibits rust resistance, maintaining its structural integrity even when exposed to moisture or varying workshop conditions.

04FUNCTION
Automatic core ejection system
Once the cut is complete, a spring mechanism within the drill bit pushes the cylindrical core out of the saw body. This feature eliminates the need for manual tapping or twisting to free the disc. Additionally, dedicated chip removal holes accelerate the clearing of debris, preventing clogging and maintaining efficient cutting performance throughout the process.
DETAILS
Practical specifications and care
The 105mm diameter suits large openings in plumbing or electrical work. The package weighs 0.35 kg and measures 11 x 22 x 33 cm, indicating a compact yet sturdy carton. For optimal results, keep the drill perpendicular to the surface to avoid tilting. Wearing goggles is recommended to protect against flying particles, especially when working with abrasive materials like gypsum board.

About this product
[Material] The hole saw is made of M42 bi-metal, which has higher hardness, higher toughness, impact resistance, wear resistance and rust resistance, equipped with drill bit hardware. The drill has sharp edges, less vibration, more stable operation, and can cut holes quickly and balanced.
[Hole Clearing] After drilling, the spring on the drill bit will automatically push the disc out of the saw; the drill bit is equipped with a chip removal hole, which improves the chip cleaning speed.
[Application] Suitable for drilling holes in gypsum board, plastic, wood, plywood, thin iron plate, thin stainless steel plate, thin aluminum plate, etc. It can be used in plumbing engineering, electrical engineering and various drilling work, suitable for electric drills and cordless electric drills.
[Note] 1. Please be sure to use it perpendicular to the component. Do not tilt the drill from the middle. 2. Rotate at low speed to start hole saw cutting. 3. When cutting metal, sprinkle cutting oil or water on it to lubricate and cool. 4. Wear goggles, and other protective equipment when using.
