Durable design – built to deliver up to 2X the lifespan of standard impact-rated hole saws.
Bi-Metal 8-TPI teeth – precisely engineered for fast, clean, efficient cutting in sheet metal.
Extreme performance – optimized for today’s high-torque impact drivers, cutting up to 40% faster than conventional models.
The fully automated tooth tip welding process and advanced rounding machines ensure that the high-quality raw material for the cutting edge is securely welded to the body with the highest level of concentricity and square circle. This allows for smooth cutting when sawing. The open hole is guaranteed to remain geometrically round in shape.
It can simultaneously preserve maximum structural integrity while maintaining the thinnest possible wall thickness.
This design makes precise cuts easier without the usual "walking" or grabbing the standard hole saws do. You don’t need to start from the edge—just set it directly where you want the cut and drive through. This makes it especially effective for sheet metal, electrical Box Repair, and precision applications.
Depth stop – a raised midsection on the body prevents accidental breakthrough and ensures precise hole depth.
Pilot bit spring – automatically ejects plugs for faster workflow.
1/4″ hex shank – universally compatible with drills and 1/4″ hex impact drivers.
For your convenience, this hole saw is compatible with a variety of common tools, including:
Outside Diameter: 25mm (1 inches)
Material: High speed steel
Shank: 1/4″ hex shank
To prevent tooth chipping, maintain a steady cutting motion and avoid sudden, forceful impacts between the cutting edge and the material.
When cutting thicker materials, applying water or coolant during operation is recommended to keep the tool cool and extend its life.
The performance and durability of a hole saw depend on the quality of its three core parts:
Each component plays a critical role. If any one of them fails, the overall cutting efficiency and reliability of the tool suffer. Many users have experienced broken drill bits during use—often a sign of inferior material or poor design.
Even the best drill bits can break if misused, but ours are crafted from premium high-speed steel (HSS) to greatly reduce that risk. The material provides excellent hardness and toughness, giving you confidence in high-torque drilling tasks while maintaining long service life.
Additionally, some customers may experience difficulty drilling holes in steel components (as shown in the image), resulting in rapid tool wear and an inability to bore through the steel.
There are two main reasons for this:
1. The material of the tooth tip differs, specifically whether or not it contains 8% cobalt. All raw materials for our tooth tips are inspected before being stocked.
2. The steel may be harder or thicker. In such cases, we strongly recommend using the TCT hole-cutting tool shown below for drilling.
The 8% cobalt-tipped teeth are designed for superior penetration across a wide range of materials, including wood, plastic, synthetic resin, aluminum, cast iron, and steel. A reinforced base cylinder, paired with a strong central shaft connection, adds outstanding stability during demanding hole-cutting operations.
Our hole saw cylinders are produced on advanced rounding machines, resulting in high concentricity and balance. This precision engineering minimizes vibration, ensures smoother cutting action, and leaves behind cleaner, perfectly round holes—a major advantage when working on professional projects.
