Norske’s NBHSI602 is a thin-wall bi-metal hole saw featuring industrial-grade M42 high speed steel with 8% cobalt, enhancing wear resistance and tooth strength. Its 3-tooth-per-inch design allows faster cutting with burr-free edges, perfect for thin sheet metals up to 1/8″ thick. The 1/4″ hex shank ensures a secure fit in impact drivers, maximizing torque transfer. This tool is ideal for electrical, HVAC, and general metalworking applications requiring precise, clean holes.
Buying Guide for Hole Saws Compatible with Impact Drivers
Choosing the best hole saw for your impact driver depends on several important factors. Here’s what to consider before purchasing:
Material Compatibility
Hole saws come in different materials suited for cutting various substrates. M42 high speed steel with cobalt offers excellent wear resistance and heat tolerance for metals like stainless steel and aluminum. Bi-metal saws are versatile for metals and wood, while thin-wall designs suit sheet metal cutting with faster speeds and less material waste.
Shank Type and Size
A 1/4-inch hex shank is standard for impact drivers, allowing secure grip and optimal torque transfer. Ensure the hole saw’s shank matches your tool’s chuck size to prevent slippage. Some kits include arbors or adapters to extend compatibility.
Hole Saw Sizes
Select sizes according to your typical applications. Kits with multiple sizes provide flexibility for different projects, while single hole saws suit specific tasks. Consider common electrical or plumbing sizes if working on specialized installations.
Tooth Design and TPI
The number of teeth per inch (TPI) influences cut quality and speed. 8 to 10 TPI is typical for bi-metal hole saw teeth, balancing fast cutting with relatively smooth edges. Thin-wall saws may have fewer teeth to facilitate burr-free cuts on thinner materials.
Durability and Wear Resistance
Look for hole saws made with premium materials like M42 with cobalt additive for longevity, especially when drilling stainless steel or other hard metals. Increased wall thickness and optimized tooth geometry improve durability and reduce tooth loss.
Cutting Depth and Speed
Check the maximum cutting depth to ensure it will meet your material thickness requirements. Fast chip removal features help maintain cutting speed and reduce binding on deep cuts.
Compatibility with Impact Drivers
Not all hole saws are rated for impact drivers. Choose models specifically designed or tested for high torque impact application to avoid damage to both the tool and the hole saw. Hex shanks and sturdy construction are indicators.
