About Sound Levels
Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.
Grinding Bits for Nonmetals
Almost as hard as diamond, these tungsten carbide bits cut through nonmetals without generating heat.
Bits are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Grinding Bit Sets for Nonmetals
Best for grinding composites, fiberglass, plaster, plastic, rubber, and wood without generating heat, these sets include a selection of our most popular tungsten carbide bits. The bits are also known as mounted points and die grinder bits.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Hazardous Location Upblast Roof-Mount Exhaust Fans
With a UL-listed motor, these fans can be used in hazardous environments with combustible gases and dust to draw stagnant and humid air out through your roof, forcing it up and away from its surface.
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.
