About WB / WP / WC 80° Trigon Positive Inserts (W-Style)
The ISO 1832 W-shape family delivers an 80° trigon cutting edge with positive clearance — a specialty geometry used primarily for small-diameter boring and profiling on Swiss-type lathes. Tungaloy's W-family in this collection includes:
- WB (5° positive clearance) — 7 SKUs. The dominant 80° trigon positive with chip-breaker. All WBGT in this catalog are left-hand (L) orientation, IC sizes 3.0 / 6.0 / 8.0 mm, with W08 and W11 wiper chip-breaker variants.
- WP (11° positive clearance) — Currently not stocked (sourced on-demand). Sharper 11° rake for ultra-precision profiling.
- WC (7° negative clearance) — Currently not stocked (sourced on-demand). Balanced negative rake.
WB inserts are the specialty geometry for small-diameter precision boring — the 80° trigon shape distributes cutting forces evenly on tiny boring bars (3-8 mm diameter). Tungaloy's WBGT catalog in this collection features the W08 and W11 wiper chip-breakers for high-feed finishing with mirror surface. Common applications include medical bone screws (Ø 1.5-3 mm), watch parts (Ø 0.5-2 mm), and electronic connector pins.
The 7 SKUs in this collection are all WBGT (ground periphery, precision boring) with 2 grade options: GH110 (PVD Al-rich for stainless steel 304/316) and NS9530 (cermet for mirror surface finishing on steel). The 3.0 mm IC is the most common (4 SKUs), with 6.0 mm and 8.0 mm IC for larger boring applications.

By Workpiece Material
- Stainless Steel 304/316 (Medical, Watch) — WBGT 03-W08 GH110 (2 SKUs, PVD Al-rich)
- Mirror Finish on Steel — WBGT 03/06/08 NS9530 (5 SKUs, cermet)
By IC Size
- 3.0 mm (WBGT 03): Smallest, micro boring. 4 SKUs (2 GH110 + 2 NS9530).
- 6.0 mm (WBGT 06): Medium precision boring. 2 SKUs (NS9530).
- 8.0 mm (WBGT 08): Larger boring. 1 SKU (NS9530).
By Carbide Grade
- GH110 (PVD Al-rich) — Tungaloy's PVD grade for stainless steel 304/316 and high-temperature alloys. Excellent built-up edge resistance. 2 SKUs (WBGT 03).
- NS9530 (Cermet) — Tungaloy's premium cermet grade for mirror surface finishing (P05-P15). 5 SKUs (WBGT 03/06/08).
By Wiper Chip-Breaker
- W08: 4 SKUs. Tungaloy's narrow wiper geometry for IC 3.0 mm — high feed + mirror surface for the smallest boring.
- W11: 3 SKUs. Tungaloy's wider wiper geometry for IC 6.0 / 8.0 mm — high feed + mirror surface for medium boring.
WB vs WP vs WC — 80° Trigon Positive Variants
Where does the WBGT 5° positive fit among the 80° trigon family? This table compares WB (5° positive) against WP (11° positive) and WC (7° negative).
| Attribute | WB (80° 5° pos.) | WP (80° 11° pos.) | WC (80° 7° neg.) |
|---|---|---|---|
| Shape | 80° trigon positive | 80° trigon positive | 80° trigon negative |
| Clearance | 5° (positive) | 11° (positive, sharper) | 7° (negative) |
| Edge strength | ★★ | ★ (weakest) | ★★★★ |
| Edge sharpness | ★★★★★ (sharpest positive) | ★★★★★ | ★★★★ |
| Best for | Micro boring, profiling | Ultra-precision profiling | Stainless profiling |
| Typical IC range | 3-8 mm (Swiss-type) | 3-8 mm (Swiss-type) | 3-8 mm (Swiss-type) |
| Common holders | SWUB / EWUB (Tungaloy positive 80°) | EWUP (Tungaloy positive 80° 11°) | EWUN (Tungaloy negative 80°) |
| Common workpiece | Stainless, medical, watch | Steel, precision parts | Stainless 304/316 |
| Catalog count (Tungaloy) | 7 (this collection) | 0 (not stocked) | 0 (not stocked) |
| Best grade pairing | GH110, NS9530 | NS9530 (cermet) | US735, NS9530 |
Bottom line: Pick WBGT (5° positive) for the standard micro-boring geometry — Tungaloy's most common 80° trigon for Swiss-type lathes. The 5° rake provides a sharp edge for profiling and small-diameter finishing. WPGT (11° positive, sharper) and WCGT (7° negative, stronger) are not currently stocked but can be sourced on-demand within 5-7 days for specific applications.
How to Choose the Right WB 80° Trigon Positive Insert — 3-Step
Step 1 — Identify the Workpiece
- Stainless steel 304/316 (medical, watch): WBGT 03 with GH110 grade (PVD Al-rich).
- Mirror finish on steel (precision parts): WBGT 03/06/08 with NS9530 cermet.
Step 2 — Pick the IC Size
- 3.0 mm (WBGT 03): Micro boring for medical bone screws (Ø 1.5-3 mm) and watch parts. 4 SKUs.
- 6.0 mm (WBGT 06): Medium precision boring. 2 SKUs.
- 8.0 mm (WBGT 08): Larger boring. 1 SKU.
Step 3 — Verify Holder Compatibility
- WB (80° positive): Use Tungaloy SWUB-type positive boring bar with 80° lead angle and W-pocket.
- Verify IC to bar pocket: WBGT 03 needs 3 mm pocket; WBGT 06 needs 6 mm; WBGT 08 needs 8 mm.
- Common boring bar diameters: WBGT 03 → 4-5 mm bar; WBGT 06 → 7-9 mm bar; WBGT 08 → 9-12 mm bar.
