Kyocera TT32R5502 KW10 Grade Uncoated Carbide, Indexable Threading Insert
Product Overview
The Kyocera TT32R5502 is a KW10-grade uncoated carbide indexable insert designed for external threading. Manufactured in Japan under ISO 9001:2015 quality standards, this insert combines an ultra-fine grain substrate with precision-ground geometry to deliver excellent surface integrity, optimized chip flow, and prolonged tool durability in demanding CNC environments.
Engineered for right-hand applications, the TT32R5502 features a partial 60° thread profile compatible with Metric (M) and Unified (UN) thread standards. Each insert provides three usable cutting edges, making it a cost-effective solution for high-volume production shops.

Recommended Applications & Workpiece Materials
The KTT series threading insert is optimized for external threading across a broad spectrum of workpiece materials. The KW10 grade delivers excellent surface integrity on cast iron and non-ferrous alloys.
- Cast Iron: Grey cast iron (FC250, FC300), ductile iron (FCD500) — stable threading at high speeds
- Non-Ferrous Metals: Aluminum alloys (6061-T6, 7075), brass (C36000), bronze — excellent thread surface integrity
- Titanium Alloys: Ti-6Al-4V, Ti-5Al-2.5Sn — controlled cutting forces prevent work-hardening
- Plastics & Composites: PEEK, GFRP — sharp edge prevents melting and burr formation
Application Map by Operation
| Operation | Suitability | Remarks |
|---|---|---|
| External Threading | ★★★★★ | Primary design intent |
| Internal Threading | ★★★☆☆ | Requires minimum bore diameter check |
| Taper Threading | ★★★★☆ | Partial profile supports NPT/BSPT |
| Trapezoidal Threads | ★★★☆☆ | Partial profile — limited flank engagement |
Recommended Cutting Conditions
Parameters below serve as starting points. Optimize based on machine rigidity, coolant delivery, and workpiece condition:
| Material | Vc (m/min) | Passes | Infeed (mm) | Coolant |
|---|---|---|---|---|
| Grey Cast Iron | 60–120 | 4–7 | 0.05–0.15 (radial) | Dry / Compressed air |
| Aluminum Alloy | 150–300 | 3–5 | 0.03–0.10 (radial) | Water-soluble / MQL |
| Brass / Bronze | 80–180 | 3–5 | 0.04–0.12 (radial) | Dry preferred |
| Titanium Alloy | 15–35 | 5–9 | 0.02–0.08 (radial) | High-pressure coolant |
Operating Guidelines
- Tool Setup: Ensure threading toolholder center height is within ±0.02 mm of spindle centerline to prevent thread form distortion.
- Edge Inspection: Visually inspect insert cutting edge under 10× magnification before installation. Replace if micro-chipping exceeds 0.05 mm.
- Workpiece Runout: Maintain TIR below 0.01 mm at the cutting zone. Excessive runout accelerates localized wear on thread flanks.
- Coolant Strategy: For cast iron and brass, dry machining is preferred to avoid thermal shock. For titanium, apply high-pressure coolant (70+ bar) directed at the cutting edge.
- Speed Ramping: Start at 70% of recommended Vc for the first 5 parts, then increase to 100% once tool wear stabilizes.
- Insert Indexing: Rotate to fresh edge every 30–45 minutes of cutting time or when flank wear (VB) reaches 0.15 mm, whichever occurs first.
- Storage: Keep inserts in original packaging until use. Avoid contact between cutting edges during storage to prevent chipping.
