DESCRIPTION:

These NPT Pipe Taps are used for tapping thermocouple and boost gauge fitting holes. The 1/4"NPT Tap (larger tap pictured above) is used for some thermocouples requiring a 1/4"NPT hole.  The 1/8"NPT Tap (smaller tap) is used for for tapping boost gauge fitting holes in intake manifolds and most thermocouples. Made in USA.
   
Also available are Heavy Duty Short Length drill bits.  These bits are High Speed Steel and Black Oxide coated for superior aiding in wear resistance.  They feature a 135 point and are shorter than standard jobber length drill bits.  Their short length reduces deflection for improved accuracy and makes them less prone to breakage.  They are ideal for tight spaces.
