An electrical power drill consists of a handle, a drill 1. , an on/off switch, rotation speed and direction control devices, and a 2. . It can be either corded or cordless. Its main functions are to 3. holes and to drive 4. . A soldering iron features an insulated 5. and a metal 6. . It is used to join two metal objects together by melting 7. . A reciprocating saw includes a handle, a 8. blade, and variable 9. . It can be used vertically or 10. , and it is designed to cut through 11. and 12. movement of its blade. An angle grinder has a rotating 13. supporting an 14. disc, a 15. -angled handle, and adjustable rotating speed. It is primarily used to grind surfaces. Finally, a sander consists of a circular head with 16. attached to it, enclosed in a plastic case. It can be used manually or attached to a 17. , and its purpose is to smooth surfaces by 18. .
