Objectives

• Differentiate the different categories of files wit 100% 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

• There are several different sizes of round files though.

Half Round File

– 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

• Because of this, you should always push a file and never drag it.

• 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
