So if you’re in the market for a screw extractor set that will last a lifetime, WoodRiver is the way to go.

In this buying guide, I’ll cover everything you need to know about WoodRiver screw extractors – from what they are and how they work, to detailed reviews and tips on how to use them. I’ll also compare WoodRiver to other major brands on the market so you can make an informed decision when purchasing your own set. Let’s dive in!

What is a WoodRiver Screw Extractor?

A screw extractor is a speciality tool used to remove damaged screws and bolts that have stripped, broken or rusted in place. It grips onto the damaged screw and reverses it out when turned counter-clockwise.

WoodRiver offers a range of professional grade screw extractors made from hardened steel. They are designed to bite into soft metals like aluminum, brass, copper and steel. The extractors have a fluted square shaft that self-centers in the screw recess when turned. This prevents them from slipping out or rounding off the screw further.

Compared to cheap, imported screw extractors, the quality and durability of WoodRiver’s extractors are far superior. They are precision machined in the USA from SAE 4140 alloy steel which is hardened to over 60 HRC for strength. The extractors won’t snap or deform, even when dealing with the most stubborn and damaged screws.

How to Use a WoodRiver Screw Extractor

Using a WoodRiver screw extractor to remove a damaged screw is a straightforward process:

1. First, you’ll need to drill a pilot hole into the center of the screw using a drill bit that is slightly smaller than the outside diameter of the extractor. This pilot hole allows the extractor to get a good “bite” on the metal.
2. Select the appropriately sized WoodRiver extractor for that screw based on the original screw diameter. Gently insert the extractor into the pilot hole and align it to fit into the screw head recess.
3. Use an adjustable wrench or pliers to grip the square end of the extractor. Turn it counter-clockwise to back the screw out. Apply firm downward pressure but don’t over tighten.
4. Once the screw begins turning out, keep turning counter-clockwise with the extractor to completely remove the screw. Take care not to break the extractor or damage the threads it has latched onto.
5. If the screw refuses to budge, apply penetrating oil around it to loosen rust and corrosion. Let the oil work for 10-15 minutes before trying again. Oversize extractors can also generate more force when needed.

That’s all there is to it! The key with any screw extractor is patience and using the proper sized pilot hole and extractor. Rushing the process can damage the extractors or screw further.

Materials Used in WoodRiver Screw Extractors

As mentioned earlier, WoodRiver manufactures their professional grade screw extractors from SAE 4140 steel. This high-carbon chromium alloy steel is significantly stronger than lesser grades of steel.

After machining the extractors, WoodRiver heat treats them to over 60 HRC on the Rockwell hardness scale. This hardens the steel to prevent deformation under load. It also allows the sharp extracting flutes to bite into stubborn screws without dulling or snapping.

The final finishing consists of black oxide coating. This protects the extractors from corrosion and gives them a slick dark finish. It also provides low friction grip when turning the extractors in place.

Overall, the 4140 alloy steel and heavy-duty heat treated construction allow WoodRiver extractors to tackle stuck screws that would damage lesser tools. The extractors also won’t bend or break due to over-straining. This rugged reliability is what makes them popular for automotive and industrial applications.

WoodRiver vs Other Brand Extractors

WoodRiver screw extractors have a well-earned reputation for quality and durability. But there are other major screw extractor brands on the market worth considering:

• Irwin – Known for their Vice-Grip locking pliers, Irwin also makes decent extractors. But they are cheaper quality Chinese-made tools that can snap under too much torque.
• Craftsman – Once a reputable USA-made brand, most Craftsman extractors are now cheaper imports. They tend to deform and dull easily compared to WoodRiver.
• Harbor Freight – Very low-cost import extractors that are hit and miss in terms of longevity. Only worth buying for occasional DIY use.
• Vampliers – Known for innovation, Vampliers makes stainless steel extractors in the USA. Good quality but quite expensive.
• Grabit – Specializes in screw removing drill bits but also makes extractors. Decent alternative to WoodRiver but not as durable.

When you compare material quality, construction and longevity, WoodRiver extractors stand out as the best choice for professional use. The premium 4140 steel and heat treating allow them to outlast cheaper extractors many times over. For serious automotive or construction jobs, WoodRiver is easily worth the extra investment.

How to Remove a Stripped Screw with WoodRiver

Removing a stripped screw is one of the toughest challenges an extractor faces. Here are some tips when using a WoodRiver extractor on stripped screws:

• Properly center and seat the extractor in the screw recess before turning. This prevents cam-out damage.
• Drill a piloting hole that is 50-70% of the screw diameter to get the best grip. Too small won’t grab and too large reduces torque.
• Use penetrating lubricant like PB Blaster or Liquid Wrench to loosen the threads first. Allow time to work before extracting.
• Start turning slowly and increase pressure gradually. A jammed screw can suddenly break free causing over-torque damage.
• If the screw won’t turn after several attempts, try a larger size extractor for more grip and torque.
• A small torch can be used to heat a very stuck screw which expands the metal for easier removal. Apply penetrating lube after heating.
• If a screw head is too damaged to grip properly, cut a slot with a Dremel cutoff wheel to provide a slot for the extractor.

Patience and using proper technique is key for stripped screws. Let the WoodRiver extractor do the work by slowly biting into the damaged screw threads.

Maintaining WoodRiver Extractors

Like any precision tool, proper care and maintenance will keep your WoodRiver extractors in peak operating condition. Here are some tips:

• Avoid over-torquing extractors which can damage the tips and fracture the shafts. Allow them to bite and back screws out gradually.
• Only use extractors on appropriate soft metal screws – they aren’t designed to be used on extremely hard metal or objects.
• Use a lightweight machine oil to prevent rusting and keep the flutes sliding smoothly. Wipe down after each use.
• Don’t hammer or pry with extractors as this can damage the precisely ground flutes. Use only for turning.
• Store extractors properly when not in use. Hang larger ones and keep smaller ones in a protective case.
• Periodically inspect each extractor for chips, cracks or distortion. Damaged extractors should be replaced.
• Remove metal shavings with compressed air and re-sharpen extractors occasionally if tips become dull.

Following these care tips will maintain the effectiveness of your WoodRiver extractors for many years to come. Proper use and storage is key to their longevity.
