S50U DDQNL boring bar — 50 mm shank, DN-- 1506 compatible, left-hand cut

The S50U DDQNL is a precision boring bar designed for turning and internal machining with DN-- 1506 indexable inserts in left-hand cutting applications.

• 50 mm shank diameter for stable clamping
• 65 mm cutting height for deep operations
• Compatible with DN-- 1506 indexable inserts
• Left-hand cutting direction for specialised turning

Improved process stability for precision boring

The design delivers stable clamping and consistent cutting geometry by combining a substantial 50 mm shank with a 63 mm overall diameter, which reduces vibration during heavy cuts. This stability translates into improved repeatability and surface quality when machining bores or internal features. Operators and production engineers benefit from fewer tool offsets and reduced rework, since the robust configuration minimises chatter and maintains insert position under load.

Clear compatibility and straightforward tooling choices

Compatibility with DN-- 1506 indexable inserts makes selection and stocking straightforward for workshops that already standardise on DN-- series tooling. The bar is built to accept DDQN-style holders for those inserts, ensuring correct seating and secure clamping of the insert. The left-hand cutting orientation is specified for operations that require reversing the cutting direction; this avoids ambiguity at the machine setup stage and supports systematic tool planning across CNC turning centres.

Dimensioning that supports shop-floor planning

With a total length of 350 mm, a 65 mm cutting height and a declared mass of approximately 5.166 kg, the bar suits medium to heavy-duty turning operations where reach and rigidity matter. The ISO designation S50U DDQNL identifies the shank and insert interface clearly, simplifying procurement and tool management. The specified 107.5° cutting angle ensures effective chip control with the matched DN-- insert geometry, enabling predictable machining feeds and depths.

FAQ

Which inserts fit this boring bar?
The S50U DDQNL boring bar is specified for DN-- 1506 indexable inserts and accepts DDQN-style insert holders designed for that insert family.

Is the cutting direction fixed for left-hand operations only?
Yes, the tool is supplied for left-hand cutting; the geometry and insert orientation are optimised for left-turning applications.

What are the key dimensions to check for machine compatibility?
Check the 50 mm shank diameter, the 350 mm overall length and the bar diameter 63 mm to ensure the S50U DDQNL fits the turret and provides sufficient clearance.

Can the S50U DDQNL be used on heavy-duty turning tasks?
The combination of a solid 50 mm shank, a 65 mm cutting height and a mass of about 5.166 kg provides rigidity suitable for medium to heavy-duty operations when used with appropriate feeds and machines.
