35 Pcs Screw Extractor and Left Hand Drill Bits Set - Easy Bolt

In this review of the 35 Pcs Screw Extractor and Left Hand Drill Bits Set, the bottom line is simple: this kit is aimed at DIYers and mechanics who need a practical, all-in-one solution for removing broken or stripped bolts without resorting to drilling out whole assemblies. The set pairs 16 left-handed cobalt drill bits with 19 extractors, offering a joined approach where the left-handed bits can help spin a bolt out while the matched multispline and spiral extractors bite into damaged fasteners. It is especially useful for automotive jobs like oil pan bolts and general workshop maintenance.

Key Features

• Versatile combination: The 35pc mix of 16 left hand cobalt drill bits, 13 multispline extractors and 6 spiral extractors covers a wide range of common bolt sizes so fewer trips to the tool box are needed.
• Precision & sharp: Titanium coated HSS drill bits with a 135 degree tip profile cut easier into metal and reduce axial resistance to protect surrounding material during removal.
• Lefthanded flute design: Using the bits in reverse with an impact wrench can help spin out broken bolts before an extractor is needed, speeding some repairs.
• CrMo multispline extractors: Hardened chromiummolybdenum extractors resist fracture and match laseretched sizes for easier selection during a job.
• Spiral screw extractors: The spiral flutes embed into damaged fasteners and increase grip as torque increases, useful for deeply seated or rounded bolts.
• Organized storage: A heavy duty blow molded case keeps the set organized and portable so the kit is ready at the workbench or in a portable tool bag.

Who It's For

This kit is well suited to home mechanics, hobbyists, and small repair shops that frequently encounter stripped or broken bolts on engines, bodywork, or machinery. The combination of lefthand drill bits and both multispline and spiral extractors makes it practical for varied fastener damage and tight spaces where different extractor styles perform better.

Those who should look elsewhere include professionals who need dedicated, highwear items for constant heavy use or users who primarily work with stainless steel fasteners; the manufacturer specifically advises against using the included drill bits for stainless steel and some customers have reported mixed durability on the bits under heavy loads.

Pros & Cons

Pros

• Comprehensive 35pc assortment reduces the need to buy separate extractors and bits.
• Titanium coated HSS bits with 135 tips and lefthand design improve cutting and removal chances.
• CrMo extractors and spiral types provide toughness and increased grip for embedded screws and bolts.
• Sturdy blow molded case keeps items organized and transportable.

Cons

• Some users report mixed drill bit durability, so heavy daily use may require occasional replacement.
• Not recommended for stainless steel drilling, limiting use with certain fastener materials.

Frequently Asked Questions

Can I use these drill bits for stainless steel?
The manufacturer advises against using the included drill bits on stainless steel; they are best used on common automotive and workshop metals.

Will the lefthand bits extract a bolt by themselves?
Lefthand bits can sometimes spin a broken bolt out when used with an impact wrench in reverse, but extractors are provided for bolts that do not turn.

Are extractor sizes easy to identify?
The multispline extractors are laser etched with sizes to match the corresponding left drill bits for straightforward selection.
