Finally you can notch without a grinder! These are excellent quality bi-metal hole saws at a great price (compare to other 4+ inch deep hole saws at over $80 a piece!). Stock up and be prepared for any notching job, even off-angle. SEE NOTES – READ WHOLE DESCRIPTION.
*High Quality M42 HSS teeth stay sharp
*Bi-Metal Construction for safety/longevity and shatter resistance
*4/6 TPI variable pitch
*Extra Deep 4.0″ cutting depth
*5/8-18 threads on 1 1/4″ cutting diameter and larger (so each one of these deep saws uses our standard “Large” arbors)
These are our design and they are imported.
Max angle you can notch (from perpendicular, like a “T” notch) on each saw, at the end of the tube (like you would normally notch), without using a grinder like you always have:
1.50 – 68 degrees
1.625 – 66 degrees
1.75 – 64 degrees
2.00 – 60 degrees
Fitment notes- These work with many notchers (they have the same threads as any other hole saw). Check your notcher to see if you have room to run these. On our VersaNotcher, we recommend an extended frame, which we sell. All notchers are shipping with this extended frame standard as of the release of these longer hole saws.
