BLU-MOL 556 Bi-Metal Hole Saw
The BLU-MOL 556 is a bi-metal hole saw designed for cutting holes in a range of materials. It suits professional tradespeople and DIY users who need a reliable cutting accessory for power tools. The 3-1/2 inch diameter provides a specific hole size for common installation tasks. This accessory is built for standard drilling applications.
HSSE-Co8 Bi-Metal Construction
The hole saw features HSSE-Co8 bi-metal construction for durability and cutting performance. It offers a cutting depth of 1-7/8 inches to handle thicker workpieces. The design is not impact rated, so it is intended for standard rotary drilling rather than impact drivers. This specification defines the tool's capability and operational limits.
For Standard Rotary Drilling Tasks
This hole saw fits users cutting wood, plastic, or metal with a standard drill press or handheld drill. It is not suited for applications requiring an impact-rated accessory or for buyers needing a different diameter. Users requiring deeper cuts or specialised tooth geometries should consider other options. The tool addresses a specific hole size and depth requirement.

Questions about this item
When will the bi-metal teeth on the BLU-MOL 556 hole saw need replacement?
The bi-metal teeth wear gradually; replace the saw when cutting speed drops noticeably or teeth become rounded, as resharpening is not practical for this construction.
What limit appears first during continuous drilling with this 3-1/2 inch hole saw?
Heat buildup in the teeth and the 1-7/8 inch cutting depth typically limit sustained use before the tool itself fails, so pause to clear chips and cool the saw.
How much noise and heat does the BLU-MOL 556 generate when run all day?
Expect typical hole-saw noise levels and moderate heat at the cutting interface; use cutting fluid and proper speed to manage temperature during extended sessions.
