Product Features and Benefits

High precision: Cuts grooves and recesses accurately with smooth edges.
Durable and strong: Solid carbide material resists wear and heat during cutting.
Stable performance: Reduces vibration for consistent groove quality.
Versatile use: Suitable for steel, stainless steel, cast iron, aluminum, and copper.
Long tool life: Maintains sharp edges longer, lowering replacement costs.

How to Use

Mount the carbide internal grooving tool securely in the tool holder. Adjust the tool length for proper groove depth. Select the correct insert or blade for the material. Use proper cutting speed and feed rate. Apply coolant to improve tool life and surface finish.

Common Questions

Q1: How do I choose the right carbide internal grooving tool?
A: Choose a tool size that fits your hole diameter and groove width. Ensure the shank fits your lathe holder.

Q2: Can it cut deep internal grooves?
A: Yes, but for very deep grooves, use a longer grooving bar or step grooving to reduce vibration.

Q3: What materials can I machine?
A: Steel, stainless steel, cast iron, aluminum, and copper can be machined.

Q4: How can I extend the tool life?
A: Use proper cutting parameters, reduce vibration, and apply cutting oil or coolant.
