Left-Hand Drill Bits: A Buying Guide for the Reverse Revolution
Left-hand drill bits are special. They spin in the opposite direction of regular drill bits. This is important for removing broken screws or bolts. They are also good for drilling into things where a right-hand bit might get stuck. This guide will help you pick the right left-hand drill bit.
Key Features to Look For
You need to know what to look for when buying these bits. Here are some important features:
- Flute Design: This is the spiral groove along the bit. It helps remove material as you drill. Look for bits with well-designed flutes. They should be deep enough to remove chips quickly.
- Point Angle: The point angle is the angle at the tip of the drill bit. Common angles are 118 degrees or 135 degrees. A 135-degree angle is usually better for harder metals. It starts the hole easier.
- Shank Type: The shank is the part that goes into the drill. Common types are round and hex. Round shanks work in most drills. Hex shanks are good for quick changes.
- Size Range: Make sure the set has the sizes you need. Think about the screws or bolts you’ll be removing. Also think about the materials you will be drilling into.
Important Materials
The material of the drill bit makes a big difference. Here are the main materials you should know about:
- High-Speed Steel (HSS): This is a common and good choice. HSS bits are strong and can handle many materials.
- Cobalt: Cobalt bits are even tougher than HSS. They are better for drilling into hard metals like stainless steel.
- Titanium Nitride (TiN) Coated: These bits have a coating that makes them harder and more heat-resistant. The coating helps the bit last longer.
Factors That Improve or Reduce Quality
Quality is important. It affects how well the drill bit works and how long it will last.
- Manufacturing Process: Look for bits made with precise manufacturing. Good bits are made with care.
- Heat Treatment: Proper heat treatment makes the bit stronger. It can handle high temperatures.
- Sharpness: A sharp drill bit cuts better. It also lasts longer.
- Brand Reputation: Some brands are known for making good tools. Research the brand before you buy.
User Experience and Use Cases
Left-hand drill bits are great for specific jobs.
- Removing Broken Fasteners: This is their main job! Use them to remove broken screws or bolts.
- Drilling into Tight Spaces: Sometimes, a left-hand bit is the only way to drill. A right-hand bit might be blocked.
- Extracting Screws: These bits can help extract screws that are stripped. The reverse rotation helps to loosen the screw.
- Working with Reverse-Threaded Items: Some items have reverse threads. A left-hand drill bit is needed for these.
