Boring Tools – Overview
????
What Are PCBN Boring Tools?
PCBN (Polycrystalline Cubic Boron
Nitride) boring tools are ultra-hard cutting tools
designed for internal machining (boring) of hardened ferrous
materials such as hardened steels, cast irons, and sintered alloys. PCBN is
second only to diamond in hardness but is specially engineered to withstand the
thermal and chemical challenges of cutting iron-based materials.

PCBN Boring Tools – FAQ (Top 10 Questions)
1.
What makes PCBN suitable for boring hardened steel?
PCBN has extreme thermal
stability, chemical inertness, and hardness, which allows it
to cut hardened materials that would destroy carbide tools.
2.
What materials should not be machined with PCBN?
Avoid non-ferrous materials
(like aluminum or copper) and soft steels; PCBN is optimized for hard
ferrous materials.
3.
Can PCBN boring tools be used for roughing and finishing?
Yes. Different grades and edge
preparations are available:
- Tough grades with honed edges for roughing
- Sharp edges
for finishing operations
4.
Do PCBN tools require coolant?
Typically no—they are best
used in dry cutting. However, air blast or MQL can help with chip
control and heat dissipation.
5.
What cutting speeds are recommended?
Depending on the grade and material:
- Hardened steel:
150–400 m/min
- Cast iron:
300–700 m/min
Feed and depth of cut depend on edge prep and rigidity.
6.
Can I use PCBN inserts in my existing boring bars?
Yes, if your boring bar uses ISO-standard
insert pockets, you can fit PCBN inserts like CCMT, DCGT, etc.
7.
Are PCBN inserts index able?
Yes. Most PCBN inserts are indexable
with multiple cutting edges, providing excellent cost-efficiency.
8.
Can PCBN tools be re-sharpened?
Generally, no. While
technically possible via laser or EDM grinding, it's often more
cost-effective to replace the insert.
9.
What industries use PCBN boring tools?
- Automotive
(hardened gears, crankshafts, engine blocks)
- Aerospace
(tough alloy components)
- Tool and Die
(mold bases, hardened components)
- Heavy Machinery
(cast iron housings, bearings)
10.
How does PCBN compare to carbide for boring hardened steel?
PCBN can last 10–50 times longer,
produces superior surface finishes, and allows dry machining—saving
time and coolant costs.
