[Dimensions] 4.92 inch hole saw (125mm hole cutter) 83 mm overall length, 1.2 mm blade thickness, 10 mm shaft diameter, 6 mm center drill diameter.
[Material] Bimetal hole saw blade is made of high quality high speed steel, sharp, corrosion resistant, wear resistant and durable. The center drill is made of 4341 high quality steel, and the blade is made of high quality M42 cobalt-containing high-speed steel, which has good workability and toughness.
[FEATURES] LAIWEI Hole Drill's HSS blades are electron beam welded for high cutting performance. The HSS center drill has a spring that pushes out chips, which reduces the time and effort needed for chip removal, reduces impact when drilling, and prevents damage to the insert and hole.
【Usage] Can be used for drilling gypsum board, plastic, wood, plywood, thin aluminum board, etc. Suitable for handheld electric drill and cordless electric drill. If precision is required, please use a table drill or electric drill stand to drill holes.
[Note] Hole saw cutting starts from low speed rotation. Be sure to use perpendicular to the component. Do not tilt the drill bit in the center. When cutting metal, apply cutting oil or water. Please wear protective equipment such as goggles and gloves when using it.
Advantages of our Bi-Metal Hole SawsMost users prefer a bi-metal hole saw for the majority of their work because it is compatible with a wide variety of materials. It also cuts faster and smoother and with reduced vibration due to the variable pitched teeth.Hole saws have two different types of steel joined together to form the edge of the cutting end of the hole saw. High speed steel is joined to a soft spring steel to form a durable edge that will cut a multitude of materials and help provide long life. High speed steel is used on the outer edge due to its wear resistance properties and forms the cutting edge of the teeth.Soft, spring steel creates a flexible backing material that allows the hole saw to absorb impacts of the job of drilling holes in difficult-to-cut materials.A good bi-metal hole saw will easily cut through softer materials, such as plastic and wood-based items, as well as harder materials, such as steel and stainless steel.The type of high speed steel chosen by the hole saw manufacturer will contribute greatly to the performance of the hole saw. The best bi-metal hole saws will be made with high speed steel that has a high percentage of cobalt content.We use only high quality high speed tool steel in the manufacture of our bi-metal hole saws. This material contains approximately 8% cobalt to help maintain tooth hardness at high operating temperatures, which helps to maintain the teeth's sharpness of the cutting edge.Package Included1 x Bimetal Hole Saw1 x Simple Hole Saw Arbor
