How to Choose the Best Extra Long Drill Bits
Drill Bit Length
The primary consideration is the required drilling depth. Measure the distance you need to reach and add a few extra inches for a comfortable margin. Bits range from 6 inches to over 24 inches, so choose one that comfortably exceeds your project's needs.
Material and Shank Type
Material: High-speed steel (HSS) is common for general-purpose drilling in wood, plastic, and soft metals. Cobalt or titanium coatings offer increased durability and heat resistance for harder materials.
Shank: Most extra long bits have a round shank for compatibility with most drill chucks. Some may feature a hex shank for enhanced grip and reduced slippage in impact drivers or high-torque drills.
Bit Diameter and Flute Design
The diameter should match the hole size required for your application. The flute design (the spiral groove) affects chip removal. Deeper flutes are better for clearing debris from long holes, preventing binding and overheating.
Frequently Asked Questions
What are extra long drill bits used for?
Extra long drill bits are primarily used for applications requiring drilling beyond the reach of standard drill bits. This includes tasks like running wires through walls, installing plumbing, or creating deep holes for structural purposes.
How do I choose the right length?
Measure the total depth you need to drill and add an extra 1-2 inches for clearance. This ensures the bit can fully penetrate the material and still have a secure grip in your drill chuck.
Are there different materials for long drill bits?
Yes, common materials include high-speed steel (HSS) for general use, and alloys like cobalt or titanium coatings for drilling into harder materials or for increased heat resistance.
Can I use an extra long drill bit with any drill?
Most extra long drill bits have round shanks compatible with standard drill chucks. However, bits with hex shanks offer a more secure grip, especially with high-torque drills or impact drivers.
