Drilling Metal (Junior Cert Wood Technology): Flashcards

Tool for cutting or enlarging holes in metal

Measures force needed to change metal's shape

Fluid to cool & lubricate during drilling

Revolutions Per Minute - drill bit spin speed

Versatile for general metal drilling, cuts smoothly

Hard metals like stainless steel, handles high heat

Softer metals - durable with reduced friction

High-speed steel drill bits

Cobalt or titanium-coated drill bits

Continuously apply to manage heat

Goggles & gloves - protect from shavings & cuts

To avoid movement during drilling

Repeated tasks with accuracy & fewer manual errors
