Frequently Asked Questions (FAQs)
1. What is a self-feed drill bit used for?
A self-feed drill bit is primarily used for drilling large holes in wood. It features a removable and replaceable feed screw that can be easily sharpened. This type of drill bit is specifically designed to drill through even the toughest types of wood.
2. What is the difference between spade and auger drill bits?
Auger drill bits generally produce cleaner holes with smoother sides and fewer splintering. They are commonly used in construction, woodworking, and gardening. On the other hand, spade drill bits create holes with rougher sides and are typically used in areas that will be covered.
3. Are Auger bits better?
Auger bits offer several advantages over standard drill bits. They have an easier time drilling through various materials and provide greater drilling depth. Auger bits also tend to create holes with smoother and more uniform results.
4. When would you use an auger bit?
Auger bits are commonly used for drilling holes into wood. They are particularly useful for boring holes into bulkheads and general timber applications. The spiral drill bit head of an auger bit is designed to pull the bit into the wood, reducing the need for excessive pressure.
5. What is the advantage of an auger drill bit?
An auger drill bit is advantageous when you need to bore deep holes. It is suitable for use on both plastic and wood materials. The length and screw tip at the top of an auger bit make it easy to drill deep into the workpiece.
6. What is the most appropriate tool for sharpening auger bits?
To sharpen an auger bit, you can use a special file called an auger bit file. This file has single-cut teeth at either end and is specifically designed for sharpening auger bits. With a little practice, it is relatively simple to sharpen an old auger bit and restore its sharpness.
7. Can you use an auger bit in a regular drill?
For best results, it is recommended to use a low RPM (less than 600), high torque corded or cordless drill with auger bits. While Bosch Daredevil auger bits can work with any drill brand, using a Bosch 18V High Torque Impact cordless drill is ideal.
8. What are the disadvantages of auger holes?
One disadvantage of sampling by auger methods is that the samples obtained can be highly disturbed, and soils from different strata can get mixed. However, power augers can be used in stable boreholes where the hole will remain open.
