CFI Tools & Equipment Flashcards

What type of drill bit is recommended for pre-drilling pilot holes near the end of hardwood flooring planks to prevent splitting?

Answer: Brad-point bit or countersink bit

A brad-point or countersink bit creates a clean pilot hole near plank ends, preventing splitting when face-nailing close to the edge of solid hardwood.

Which type of saw blade is best for cutting hardwood flooring with minimal tearout on the finished face?

Answer: Fine-tooth crosscut blade (80-tooth or higher)

A fine-tooth crosscut blade (80 teeth or more) produces smooth, splinter-free cuts on hardwood flooring surfaces, minimizing tearout on the visible face.

A knee kicker is a flooring tool primarily used when installing:

Answer: Carpet, to stretch it over the tack strip before power stretching

A knee kicker is used in carpet installation to push carpet over tack strips and position it before using a power stretcher to achieve proper tension across the room.

What is the function of a power stretcher in carpet installation?

Answer: Stretching carpet taut across the room and hooking it onto tack strips

A power stretcher mechanically stretches carpet across the entire room from wall to wall, ensuring proper tension to prevent wrinkles, buckling, or premature loosening.

Which personal protective equipment (PPE) is most critical when operating a wet saw for cutting ceramic or porcelain tile?

Answer: Full face shield, hearing protection, and waterproof gloves

A wet saw produces water spray, ceramic dust, and high noise, requiring a full face shield (or safety glasses), hearing protection, and waterproof gloves for operator safety.

A laser level or chalk line is used during flooring installation primarily to:

Answer: Establish straight reference lines for consistent layout and alignment of planks or tiles

A laser level or chalk line creates straight reference lines that guide the layout, ensuring rows of flooring run parallel and square throughout the installation.
