Tool bits are non-rotary Cutting tools used in planers, metal lathes, and shapers. They are otherwise called a single-point cutting Tool. The cutting edge of the tool bit can be reshaped or resharpened as required. A tool holder tightly gets hold of the ground tool bit when cutting. The tool bit can be retracted or extended depending on the work. The size of the tool holder can be customized depending on the type of the work to be carried out. High-Speed Steel bearing tungstonmodybdenum is used in the making of tool bits.
Tool bits are commonly used for designing complex and small cutting tools. Tool bits can also be made from high carbon tool steels with accurate tempering and hardening features. The cutting edge of the tool bit is grounded to suit a specific machine work. Tool bits can be used for jobs like cutting grooves or threads. It contains exceptional cutting properties, which makes it suitable for cutting applications.
The major features of High-speed tool bits include:
- High hot hardness
- Exceptional wear resistance
- High edge-holding ability
- Ability to cut any type of metals
Advantages of Tool Bits
- Tool bits contain good toughness and strength
- The hardness of high-speed tool bits can reach up to 650 degrees
- High wear resistance
- Cutting speed is higher than other cutting tools
- Used for camrings and automobile valve inserts applications
- Tool bits have exceptional durability
- Low maintenance
Features and Uses of Various Types of High-Speed Tool Bits
HSS T-42 10% Cobalt
It is made from 10% Cobalt bearing High-Speed Steel. You can find these tool bits in 8.5% or 10.5% cobalt. These tool bits can be supplied with Cryogenic Treatment. Its features and uses include:
- Exception wear resistance
- Especially used for finishing or roughing operations where maximum tool life is required
- Ample toughness, which makes it suitable for all types of cutting tool applications including the ones at high speeds and temperatures
- Used for large-batch automatic lathe work and all types of boring and lathe works
HSS M-35 5% Cobalt
It is made from High-Speed Steel bearing 5% Cobalt. Its features and uses include:
- Used in workshops for normal cutting requirements
- High toughness
- It is suitable for roughing and interrupted cuts applications
HSS M-42 8% Cobalt
It is made from High-Speed Steel bearing 8% Cobalt. Its features and uses include:
- High degree of hard hotness
- High degree of wear resistance
- Provide extreme efficiency on high strength steels and difficult-to-machine alloys
Now, you know that the features and uses of each tool bit vary from each other. You need to select the right grade of tool depending on the nature of the cutting applications. Different tool grades are required for different cutting applications such as the hardness of job, cutting speed, ease of cutting, machine-ability of the job, and heat generated at the action. You need to consider the wear resistance and hot hardness features of the tool bits when selecting.
