Files and RaspsUnit 11: Hand Tools
Objectives
• Differentiate the different categories of files wit 100% accuracy.
• List some different kinds of files within these categories with 90% accuracy.

Files and Rasps
• What is a File?– A tool with a roughened surface used for smoothing
or shaping a hard material. • There are 4 categories of files. • How many of these categories do you know?– Flat file – Round file – Half round file– Triangle file
Flat File
• Can be large and used to take a lot of material off at once
• Also can be as fine as a finger nail file and used for detail work.
Round File
• There are not that many kinds of round files.
• There are several different sizes of round files though.
Half Round File
• Can have one round edge and a flat edge or two round edges.
Triangle File
• Taper• Slim taper • Extra Slim taper• Regular taper
What are some things that we use these files for?
• Flat file– Metal work• Gunsmith• Fabrication
– Wood working• Furniture maker• Bowyer
– Horse shoeing• Farrier• Rancher
• Round file– Metal work • Sharpening chainsaws • Filing in small or hard to
reach places such as the inside of a pipe
– Wood work • Cutting small round
grooves for finish work
• Half round file– Metal • One of the best
uses for this is to clean the burs out of the inside of larger diameter pipe.
– Wood working• Great for making a
concave surface on wood products
• Triangle file – Metal• Used for small
detailed work and for making square corners.
Using the file
• The teeth on a file all point away from the handle.
• Because of this, you should always push a file and never drag it.
Safety Procedures
• Safety wear– Safety glasses• to protect your eyes safe from debris
– Gloves• to keep your hands protected
Summary
• What are the 4 categories of files?– Flat file– Round file – Half round file – triangle file
• What is the correct way to use a file? – File must have a handle– Always push a file rather than pull it
• What items should we wear to improve safety?– Gloves– Safety glasses
