RT11.01N-A60 YBG201 Threading Insert
Precision Internal 60° Universal Threading for Small Diameter Boring Applications
Product Overview
"Need absolute precision for internal threads in small bores? The RT11 series with A60 profile offers the versatility you need for pitches from 0.5mm to 1.5mm."
The ZCC.CT RT11.01N-A60 YBG201 is a high-precision internal threading insert optimized for small-hole machining where space is at a premium. The "A60" designation signifies a Partial Profile 60° geometry, allowing a single insert to cover a wide range of metric and UN pitches (0.5mm to 1.5mm / 48-16 TPI).
Equipped with the YBG201 Grade, this insert features a specialized TiAlN PVD coating over an ultra-fine grain carbide substrate. This grade is specifically engineered for Steel (P) and Stainless Steel (M), providing the exceptional edge sharpness and wear resistance required for high-accuracy finishing in delicate internal threads.
Key Features
- High-Precision YBG201 Grade: Optimized for high-speed finishing, this grade offers a very sharp cutting edge that minimizes burrs and maximizes thread accuracy.
- Universal A60 Profile: Covers a versatile pitch range from 0.5mm to 1.5mm, reducing the need for multiple insert types for different small-thread specifications.
- Small Bore Specialist: The 11mm size is specifically designed for small diameter internal tool holders, providing necessary clearance and stability.
- Excellent Wear Resistance: The PVD TiAlN coating provides a robust heat barrier, essential for maintaining tolerances during continuous internal cycles.

The YBG201 Advantage
The YBG201 grade is ZCC.CT's answer to precision finishing. Unlike general-purpose grades, it utilizes a finer carbide substrate that allows for a much sharper cutting edge. For small pitch internal threads, this sharpness is critical to prevent the material from "smearing" and to ensure that the thread peaks meet strict quality standards.
Verified User Performance
"The RT11 series is perfect for our small lathe work. The A60 profile is so handy—one insert handles almost all our internal metric work from M6 to M12."
— Hiroshi M., Japan"Excellent finish on stainless steel. We use YBG201 for finishing threads and it stays sharp much longer than the previous brand we used."
— Carlos R., Spain
