The Klein Tools 33811 Drill and Driver Bit Set is a 32-piece assortment of impact-ready bits and adapters for common drilling and fastening jobs. Autoblog reported an Amazon price of $20 on October 3, 2026; that is a dated price report, not a confirmed current price or a sale claim. Check the live listing for today’s price, seller, stock, and shipping.
What the Klein Tools 33811 set includes
Klein Tools lists 32 pieces in the case, combining four small impact twist drill bits with driver bits and accessories. The drill-bit sizes are 1/4, 3/16, 5/32, and 1/8 inch.
The driver-bit assortment covers Phillips, square, Torx, and slotted fasteners in multiple sizes. The set also includes a stainless steel bit holder, a 3/8-inch square adapter, and 5/16-inch and 3/8-inch power nut drivers. Check the product listing’s itemized contents against the fasteners you expect to use; the assortment is useful only if its sizes and types match your work.

What it is—and who it suits
This is an accessory set for a drill or impact driver, not a power tool. Klein lists its applications as drilling, screwdriving, nut driving, and impact driving. It makes sense for someone who already owns a compatible tool and wants a compact collection of common bits, a few drill-bit sizes, and nut-driving options in one case.
#1 Best Overall
- ENERGY ABSORBING TECHNOLOGY: Helps extend the life of the impact driver bit with the torsional recoil system feature
- IMPACT-RATED: Steel bits are S2 impact-rated and built for heavy-duty applications
- PHILLIPS AND SQUARE BITS: Easily access hard to reach fasteners with the 3.5-Inch #2 Phillips and #2 Square bits
- STORAGE CASE: Included case is compact, can stack to cases with similar designs and is compatible with Klein's MODbox
- BIT EXTENSION: Powerful magnet on the 3-Inch bit extension secures bits in place
It may be the wrong fit if you need a particular fastener size or bit type that is not listed, or if you already own the pieces you would use. The manufacturer does not provide comparative durability tests, so the specifications do not establish that this set outlasts competing assortments.
Features, materials, and dimensions
Klein specifies alloy steel construction with a titanium nitride finish. Its listed design features include a ProFlex torsion zone, precision-machined tips, an enhanced magnetic bit holder, and a case compatible with Klein Tools MODbox sets. Klein says the torsion zone reduces stress and improves impact performance; that is the manufacturer’s design claim, not an independent test result.
Rank #2
- LOW PROFILE RATCHET: Micro-ratchet provides extra torque and access for hard-to-reach fasteners
- PROFLEX TORSION ZONE: Energy-absorbing design to reduce torsional stress, extending tool life and improving impact performance
- COMPACT STORAGE CASE: Ultra-slim profile fits tool pouches, pockets, and storage bins to be easily carried with an impact driver
- MODBOX COMPATIBLE: Back latch extends to connect to larger Klein Tools MODbox cases as well as connect to other slim-storage cases
- SECURE-PIVOT BIT STORAGE: Pivot slots firmly hold bits in place, preventing bits from falling out accidentally while providing easy bit access

Is it actually $20 at Amazon?
Autoblog’s Andrew Koopman reported on October 3, 2026 that the set was available on Amazon for $20. That report does not establish the current Amazon price, seller, stock, or shipping cost. It also characterized the price as not a discount or price cut, so the $20 figure should not be presented as a sale price. Confirm the live listing before buying.
