What is a Spiral Flute Extractor?

The spiral flute extractor has a left-hand fluting that embeds itself deeper into the metal as it is turned, so the extractor’s grip increases as resistance increases. The left-hand spiral flutes grip the wall of the hole tightly, while the right-hand spiral flutes of the drill bit remove the metal.

The spiral flute extractor is generally cylindrical, with a spiral flute running down its length. The spiral flute is usually left-handed, which will grip the hole wall tighter as resistance increases.

Process of Use Spiral Flute Extractor

1. First, drill a pilot hole in the center of the stripped screw using a drill bit that is the same size as the extractor.
2. Insert the spiral flute extractor into the pilot hole by turning it clockwise to start the threads.
3. Turn it counterclockwise to remove the stripped screw.

Some Extra Tips

1. It may not be possible to remove the screw with a drill, so use a drill bit of the correct size to drill the screw, then set the flue extractor in place with a wrench and remove the screw by turning it counterclockwise.
2. Apply pressure to the extractor while turning it to avoid stripping the threads.
3. You can also try lubricating the spiral flute extractor with WD-40 or other lubricants to help it start easier.

What is a Straight Flute Extractor?

A straight flute extractor is a tool used to remove screws, bolts, or other objects embedded in wood or other materials. The serial flute extractor has a flat flute that is straight rather than left-handed or right-handed. It allows the extractor to grip the object more securely, making removing it more accessible.

Process of Use Straight Flute Extractor

1. First, drill a hole in the stud with a left-hand drill bit.
2. Then, seat the straight flute extractor in the hole and tap it lightly with a hammer to place it.
3. Finally, turn the straight flute extractor counterclockwise with a tap wrench to remove the stud.

Spiral vs. Straight Flute Extractor: Which is better?

The best extractor type depends on the material being extracted and the specific application. In general, spiral flute extractors are more suitable for hard materials, while straight flute extractors are more suitable for soft materials. The straight flute extractor’s grip is not as firm as the spiral flute extractor’s because of its flat shape.

Cost of Spiral and Straight Flute Extractor

The cost of a spiral flute extractor bit varies depending on the quality but is typically between $3 and $7 for a single bit. A group set of spiral flute extractor bits can cost between $12 and $40. A straight flute extractor bit typically costs between $5 and $7 for a single bit, and a group setting can cost between $16 and $50.
