Frequently Asked Questions

What is the difference between TBGT, TPGH, TCMT, CCMT, WCGT, and SPMT boring insert grades?

Each insert type refers to a specific shape and geometry designed for different boring applications. TBGT and TPGH/TPGX are triangular-profile inserts suited for precision boring, while TCMT/TCGX and CCMT/CCGX are designed for general-purpose and fine finishing boring operations. WCGT inserts are wedge-style for small-diameter boring, and SPMT inserts are square-shaped for stable, high-feed boring on larger diameters.

What do the symbols ▲, ●, and ○ mean in the insert grade tables?

The symbols indicate availability and performance level: ▲ Excellent (Instock) means the grade delivers excellent performance and is available from stock; ● Good (Instock) means the grade offers good performance and is in stock; ○ On Request means the grade is available upon special order.

Which insert grades are recommended for machining stainless steel (M)?

For stainless steel (M category), grades such as DP5015, QP5125, QP5225, YP5120, and MC215 are recommended, as indicated by ★ and ☆ symbols in the work piece compatibility rows. These grades offer medium to excellent performance for stainless steel boring operations.

Can these boring inserts be used for machining heat-resistant alloys and high-hardness materials?

Yes. Grade YP5120 (indicated by ☆) is specifically highlighted for both heat-resistant alloys (S) and high-hardness materials (H) across multiple insert types including TPGH/TPGX, TCMT/TCGX, CCMT/CCGX, and WCGT series. Always verify the specific application conditions with the grade selection chart.

What does the "L" dimension refer to in the insert specification table?

The "L" dimension refers to the cutting edge length of the insert. Other key dimensions include ΦI.C (inscribed circle diameter), S (insert thickness), Φd (hole diameter), and r (corner radius). These dimensions are critical for selecting the correct insert for your boring bar and achieving the desired machining tolerances.

Which insert type is best suited for machining non-ferrous metals such as aluminum?

For non-ferrous metals (N category), the CCGX-AL and TCGX-AL series inserts with grade NA10 are the primary recommendation, as shown by ★ and ● symbols in the non-ferrous row. The -AL suffix indicates these inserts are specifically optimized for aluminum and other non-ferrous materials, featuring sharp cutting edges to minimize built-up edge and achieve excellent surface finish.
