Mastercool 70085 Inner/Outer Reamer for 3/16" to 1-1/2" O.D. Tubing

The Mastercool 70085 is a dual-purpose inner/outer reamer designed for deburring copper, brass, and aluminum tubing used in HVAC/R and automotive air conditioning systems. After cutting tubing, burrs and rough edges are left on both the inner bore and outer edge — this tool removes them quickly and efficiently with a single compact instrument.

Key Features:

• Deburrs both the inside and outside of cut tubing in one tool
• Compatible with tubing from 3/16" to 1-1/2" O.D.
• Ideal for preparing copper, brass, and aluminum tubing before flaring or brazing
• Helps ensure leak-free connections by producing clean, smooth tube ends
• Compact and lightweight — easy to carry in a service kit or tool pouch

The Mastercool 70085 is an essential hand tool for HVAC/R technicians and automotive A/C service professionals. Properly reamed tube ends reduce the risk of leaks at flared or brazed joints, making this a must-have for quality tube preparation work.
