Chroma
Intensity of color or purity
Chromated copper arsenate (cca)
A chemical preservative injected into wood to make it resistant to insect infestation or rot. CCA gives the wood a greenish tint. Copper acts as a fungicide, arsenic as an insecticide while chromium is the agent that binds everything to the wood.
Chrome-plated
Chrome plating is often used on bath items because chrome resists water and corrosion.
Chuck
Adjustable, clamp-like device, as on a drill or lathe, by which the tool or work to be turned is held.
Chuck capacity
Chuck capacity indicates the largest size full-shank cutting tool (twist drill bits on power drills) a drill's chuck can accommodate. Capacity is a good indicator of the maximum size hole a tool will comfortably bore through a hard metal surface. 1/4 And 3/8 inch drills handle most homeowner needs. Both have higher rpm output and lower torque for fast results. 1/2 Inch drills accept larger bit shanks and have higher torque for tougher jobs and prolonged use in wood, masonry and steel.
Chuck key
A chuck key is a small l or t-shaped steel piece with a gear on one end. It is used to hand-open or close a drill's chuck around a bit shank. Chuck keys vary in type and size, including universal and ratchet versions.
Chuck, combination
The adjustable, clamp-like device, as on the end of a drill or lathe, by which the tool or work to be turned is held, the combination chuck has three jaws that move simultaneously to lock the item into place.
Chuck, independent
