More questions buyers ask
What is a boring bar used for?
A boring bar is a cutting tool used in lathes and milling machines to enlarge or finish an existing hole with high precision.
What materials can these boring bars cut?
These bars are designed for metalworking but are compatible with various substrates including wood and plastic.
What is the benefit of carbide-tipped boring bars?
Carbide tips offer superior hardness, wear resistance, and heat tolerance compared to standard steel, allowing for higher cutting speeds.
How do I choose the right boring bar diameter?
Choose the largest diameter that fits the bore to maximize rigidity and minimize vibration during the cutting process.
Are these boring bars compatible with all boring heads?
They are specifically designed for 50mm MT3-M12 Morse Taper systems, but check your specific machine specifications for compatibility.
What is the recommended torque for the pre-load screw?
The recommended torque for the M6 pre-load screw is typically 0.9 to 1.0 Nm.
How many pieces are in the sets?
We offer sets of 9 pieces (12mm shank) and 12 pieces (18mm shank).
Do these tools come with a warranty?
Yes, all Pentagon machine tools come with standard manufacturer warranty support.
Can I use these for CNC turning centers?
Yes, these boring bars are suitable for both manual and CNC turning and milling operations.
How do I ensure the best surface finish?
Use the largest possible bar diameter, ensure the tool is securely mounted, and maintain proper chip evacuation.
Who should choose the 12mm shank set?
Ideal for users with 2-inch boring heads requiring precision work on smaller diameter holes.
Who should choose the 18mm shank set?
Best for heavy-duty applications using 3-inch boring heads where increased rigidity is required.
How does the 12mm set compare to the 18mm set?
The 12mm set is designed for 2-inch heads with 9 pieces, while the 18mm set is for 3-inch heads with 12 pieces for broader versatility.
Which set offers better rigidity?
The 18mm shank set provides higher rigidity due to the larger diameter, making it better for deeper or more demanding bores.
