Efficient Metal Cutting Performance

Designed for versatile metalworking, this 1-9/16-in. hole saw can be used on aluminum, mild steel, stainless steel, cast iron, copper, zinc, brass, and other non-ferrous metals and composite materials. It is a practical choice for installers, fabricators, maintenance professionals, tradespeople, and DIY users who need dependable hole-cutting performance.

Precise Hole Enlargement

The Fast Lock system also allows two compatible hole saws to be attached together for controlled enlargement of an existing hole. This feature provides a practical solution when an existing opening needs to be increased to a larger diameter.

Hex Shank for Secure Power Transfer

The compatible hex-shank system provides strong, non-slip power transfer between the drill and hole saw. A properly matched shank helps deliver efficient cutting performance and reliable operation during metal-cutting applications.

Metal Cutting Tips

• Use slower drill speeds when cutting metal to help control heat and improve hole saw life.
• Apply an appropriate lubricant when cutting most metals to reduce friction and heat buildup.
• Use cutting oil for most metal-cutting applications.
• Use turpentine when cutting aluminum.
• Cut cast iron dry without lubricant.

Choose the Proper CMT Shank

For the best results, pair the 1-9/16-in. CMT bi-metal hole saw with the appropriate CMT hex-shank high-speed drill. Hole saws up to 1-3/16-in. use the smaller shank option, while hole saws 1-9/16-in. and larger require the larger shank.

• Hole saws up to 1-3/16-in.: Use the CMT Hex Shank High Speed Drill with a 25/64-in. (10 mm) shank diameter and 7-5/64-in. length. McFeely's SKU: CMT-Sh351-HS1.
• Hole saws 1-9/16-in. and larger: Use the CMT Hex Shank High Speed Drill with a 1/2-in. (13 mm) shank diameter and 7-5/64-in. length. McFeely's SKU: CMT-Sh351-HS2.
