Core Bit Adapters for adapting different size threads to different machines
Standard core drill adapters have the following threaded hub sizes:
- 1-1/2" and under (bit diameter)= 5/8"-11 thread
- (5/8" diameter, 11 threads per inch)
- 1-5/8" and up (bit diameter) = 1-250"-7 thread
- (1-1/4" diameter, 7 threads per inch)
- * Male bottom thread is a replaceable grade 8, 5/8"-11 bolt with water way ∞ These threaded drill bit adapters are for use on Weka motors
