The Best Drills and Bits
Posted by Bob Bulmer on Fri 23rd November 2007 at 06:00 AM, Filed in Power Tools, Tools
When buying a new drill, you need to bear in mind a few key points:
Drills
• Do I want a mains powered drill? They tend to give higher revolution speeds and quicker penetration. Prices are usually cheaper than cordless versions.
• Do I want a cordless drill? Battery powered drills tend to lack the raw power of a mains connected drill, but offer real versatility without the constraints of a mains lead.
• If you’re looking for a multi purpose drill, then you’re going to want a variable speed mains drill with hammer action and reverse gear. This gives you the option to drill into concrete or masonry.
• A 13mm keyless chuck enables you to drill holes up to 32mm diameter in timber and 13mm in metal or masonry.
• A cordless drill can also offer a powered screw driver option.
• More powerful batteries are often heavier.
• Ensure that you select a cordless drill with rapid recharge.
Drill Bits
• High speed steel twist bits are used for making holes in wood and metal.
• Masonry bits are required for bricks and concrete.
• Most drill bit sets come in a variety of standard sizes. These will cover most eventualities - buy specialist bits when the need arises.
