3. Core Craft & Performance Advantages

1. M42 HSS Bi-Metal Welding Teeth, Sharp & Wear Resistant

The cutting teeth adopt M42 high-speed steel bimetallic composite welding process, with high hardness and strong heat resistance. It can continuously cut ferrous metals such as iron and steel without rapid passivation. Compared with ordinary low-carbon steel hole saws, the service life is increased by 3-5 times, and the cutting edge remains sharp after long-term repeated use.

2. Wave-Shaped Serrated Design, Fast Chip Removal & Low Vibration

Adopts special wave-shaped tooth profile layout, independent chip removal gaps between each tooth. Sawdust, metal scraps and wood chips are quickly discharged during drilling, effectively preventing material adhesion and tooth blockage. Optimized tooth pitch reduces high-speed rotation vibration, ensuring round and smooth hole walls without burrs.

3. Thickened Integral Saw Body, Anti-Deformation & Anti-Cracking

The saw cup main body is made of thickened high-toughness carbon steel with stamping and anti-rust blue coating treatment. It is not easy to deform or crack under heavy-load drilling and inclined operation by novices. Multiple reserved side chip removal windows assist rapid slag discharge and heat dissipation, avoiding overheating burning damage of the saw body.

4. Built-in Pilot Drill & Eject Spring, Convenient Operation

The equipped high-hardness centering pilot drill bit effectively solves the problem of initial drilling slipping and wandering, positioning accurately at one time. The built-in auxiliary spring automatically pushes the cut workpiece out when drilling is completed, saving manual picking time and improving continuous drilling efficiency.

5. Universal 9mm Standard Shank, Wide Tool Compatibility

9mm straight shank fits most electric drill chucks on the market stably, with large clamping contact area, no shaking or slipping during high-speed rotation drilling. It can be matched with household hand drills, bench drills and small industrial drills flexibly, adapting to diversified usage scenarios.

Practical Drilling Performance

  • Drilling Efficiency: Fast cutting for wood boards, one-hole forming in seconds; for thin iron plates with cutting fluid assistance, stable cutting without tooth jumping or tooth collapse;
  • Hole Finish: Clean hole edge with few burrs, no edge cracking for gypsum board and wood materials, reducing post-grinding work;
  • Durability: Continuous drilling of hundreds of holes on wood and thin metal materials, no obvious wear of cutting teeth, stable aperture precision;
  • Safety: Strictly implement production dimensional standards, high concentricity of finished products, low rotation jitter, effectively reducing operational safety risks.

4. Wide Application Scenarios

🏠 Home Decoration & Renovation Projects

Used for drilling socket bottom box holes, water and electricity pipeline reserved holes, lamp installation holes, range hood vent holes on gypsum board, wood boards and wall panels during home decoration. Multiple sizes meet different aperture demands of household renovation.

🛠️ Daily Maintenance & DIY Handmaking

Household maintenance and DIY enthusiasts use it to drill holes for furniture modification, PVC pipe transformation, electrical equipment panel fixing holes. Easy to operate with household electric drills, solving various daily hole-making demands.

🏭 Factory Equipment & Pipeline Installation

Workshop pipeline installation for thin iron pipe, aluminum alloy pipe, plastic pipe opening; equipment cabinet panel threading holes, ventilation duct reserved holes. Adapt to multi-material mixed drilling demands of factory daily maintenance.

🔌 Electrical & Weak Current Construction

Electrician and weak current engineering teams use it for wall wire box holes, cable through holes, distribution box panel drilling. Stable drilling does not damage the base material, improving construction standardization and efficiency.

7. Common FAQ

Q1: What materials can this bi-metal hole saw drill?

A1: It is suitable for wood, plywood, gypsum board, drywall, thin iron plate, aluminum plate, copper plate, PVC plastic plate, plastic pipe and other conventional materials. It is not recommended for thick solid steel plates and reinforced concrete.

Q2: Do I need cutting fluid when drilling metal?

A2: It is recommended to add cutting fluid or water cooling when drilling iron, aluminum and other metals, which can reduce cutting heat, prevent tooth burning and significantly extend the service life of the hole saw.

Q3: Which drills can the 9mm shank match?

A3: It is compatible with most electric drills with 10mm/13mm standard chucks on the market, including household hand drills, impact drills and bench drills, no extra adapter needed.

Q4: How to judge the hole saw needs replacement?

A4: When the cutting teeth are obviously worn flat, the drilling speed becomes extremely slow and it cannot cut into the material normally, the tooth part reaches the wear limit and needs to be replaced in time.

Q5: What is the delivery time for bulk orders?

A5: Conventional 75/90/105mm in-stock sizes can be delivered within 3 working days; customized sizes, packaging and logo orders take 7-15 working days according to the order quantity, and our factory has sufficient stable production capacity to ensure on-time delivery.
