Bosch TCW1C450 Thin Cutting Disc

This 4-1/2 inch Type 1 cutting disc is designed for angle grinders and targets professionals cutting concrete and masonry on the jobsite. The C60R-BF grit specification suits hard mineral materials and the 7/8 inch arbor fits standard grinders. It is not for metal fabrication or buyers who need a grinding wheel profile.

Rapido thin wheel design

The Rapido thin profile reduces cutting time by up to 50 percent and requires less force during operation. Vibration-free cutting minimises user fatigue while the no-burr finish eliminates rework on the cut edge. These features change the workflow by speeding up each cut and cleaning up the result.

Max RPM 15250

The single specification that decides fitment is the maximum speed rating of 15250 RPM; the angle grinder must not exceed this value. The 4-1/2 inch diameter and .045 inch thickness match the tool guard and spindle. Buyers who need a larger diameter or a different arbor size cannot use this disc.

Questions about this item

When will the 4-1/2 inch cutting disc need replacing?

The disc wears down as it cuts concrete and masonry; replace it once the diameter shrinks enough to reduce cutting depth or the wheel shows cracks.

What limits continuous cutting with the 15,250 max RPM wheel?

Heat buildup in the bond and abrasive grain is the first limit; let the disc cool periodically to avoid glazing or premature wear.

How much vibration and heat does the Rapido thin wheel produce during all-day use?

The C60R-BF specification is designed for vibration-free cutting and minimal burring, which keeps heat and operator fatigue low during extended sessions.
