Hitachi’s press release on the their new 7-1/4″ “pro-grade” circular saw touts the inclusion of “patented Internal Double Insulation (IDI) technology” which they claim reduces vibration and wear to estend the saw’s life by 200%. The core of IDI is a process that intertwines the saw’s aluminum housing with an injection-molded inner nylon core — but most Toolmongers will stop after reading “aluminum housing.” All-metal housings are all too rare now-a-days.
Other features: a 1,710-watt motor spining a no-load speed of 5,800 RPM, an electric brake, and a zero to 55-degree bevel capacity with a positive stop at 45-degrees. The base is aluminum to reduce weight, but the C7BMR is no lightweight, weighing in at 10-1/2 pounds.
When it hits shelves in the next few months, it’ll retail for around $130 and will ship with a box wrench and a 24-tooth carbide blade.
