Built for fast drilling in production assembly, aircraft maintenance, fabrication, and industrial MRO environments, the Dotco 14CNL98-51 non-reversible pneumatic drill delivers 0.9 HP with a 6,000 RPM free speed for applications that call for high spindle speed and efficient hole-making. As part of the 14CNL Series, this rear exhaust air drill is suited for dedicated forward-drilling tasks where quick cycle times, smaller drill sizes, and repetitive production work are priorities.
The 6,000 RPM speed supports rapid drilling in compatible materials when paired with the correct bit and cutting conditions. Rear exhaust helps direct spent air away from the work surface, reducing air blast around chips, fixtures, and layout marks during repetitive drilling operations.

Made in USA: 
Applications:
- Aircraft manufacturing and MRO drilling where high spindle speed is required.
- Production assembly stations performing fast, repeatable forward-drilling operations.
- Metal fabrication work using smaller drill sizes or drilling conditions suited to higher RPM.
- Maintenance departments drilling panels, brackets, fixtures, and machine components.
- Machine shops and repair benches that require pneumatic drill performance with fast cycle times.
FAQs:
- Q: What does non-reversible mean?
A: Non-reversible means this drill operates in the forward direction only. It is intended for drilling work where reverse rotation is not required. - Q: Why choose the 6,000 RPM version?
A: A 6,000 RPM drill is useful when the application calls for faster spindle speed, smaller drill sizes, or quick cycle times in compatible materials. - Q: What is the benefit of rear exhaust?
A: Rear exhaust directs spent air away from the drilling point, helping reduce air blast around chips, fixtures, and marked work surfaces. - Q: Can this drill be used for production drilling?
A: Yes. When matched with the correct drill bit, air supply, and material requirements, this pneumatic drill is suitable for repetitive industrial drilling work.
