How to find the right Hole Saw Arbors AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Hole Saw Arbors
- Thread size
- 1/2-20 threads fit small saws (roughly 9/16 to 1-3/16 in); 5/8-18 threads fit 1-1/4 in and larger The thread must match the saw, so many users need both arbor sizes.
- Shank size and shape
- 3/8 in shanks suit small arbors and lighter drills; 7/16 in hex suits large saws in 1/2 in chucks A hex shank stops the arbor from spinning in the chuck under heavy torque.
- Quick-change mechanism
- Quick-change arbors lock the saw with drive pins so you don't thread it down; they are often brand-specific They make releasing a saw and swapping sizes much faster, but check compatibility with your saw brand.
- Drive pins
- Prefer arbors with drive pins that engage the saw's back plate The pins keep the saw from tightening onto the threads until it is nearly impossible to remove.
- Pilot bit retention
- Check the pilot bit is secured by a set screw or quick-release and that replacement bits are available A worn pilot bit wanders, and some arbors only take their own pilot bits.
Brands that matter
- Milwaukee: Quick-change arbors for Hole Dozer saws.
- Lenox: Quick-change and standard arbors in both thread sizes.
- Starrett: Standard and quick-change arbors.
- DeWalt: Arbors sold alone and in hole saw kits.
What to avoid
- Arbors with no drive pins for large saws
- Round-shank arbors in high-torque drills, where they slip in the chuck
Questions
Will one arbor fit all my hole saws?
Usually not: small saws use a 1/2-20 thread and larger ones use 5/8-18, so most kits include two arbors.
