The DEWALT DWA1184 dominates budget drill bit performance with its 135° split point design that eliminates walking and starts holes instantly. The three-flats shank prevents slippage in chucks better than round-shank competitors, while the precision-ground tips cut through mild steel, hardwood, and PVC with minimal pressure. During testing, these bits maintained sharpness after 50+ holes in abrasive materials.

What separates this set is DEWALT's industrial-grade heat treatment that resists overheating better than other sub-$25 options. The metal index case keeps bits organized and protected, though the plastic latch feels less robust than pro-grade alternatives. For DIYers wanting reliable performance without premium pricing, this 14-piece covers the most-used sizes from 1/16" to 1/2".

Pros
  • 135° split point prevents bit walking
  • Three-flats shank eliminates chuck slippage
  • Maintains sharpness through repeated use
  • Organized metal storage case included
  • Covers essential sizing range
Cons
  • Plastic case latch feels flimsy
  • Limited to 14 sizes
  • Not suitable for hardened steel

Buyer's Guide

What to Look for in a Drill Bit Set

Material & Coating

Titanium nitride and black oxide coatings extend life by reducing heat buildup and corrosion. For metal, cobalt M42 is mandatory. Wood and plastic only require basic high-speed steel. Avoid uncoated bits in humid environments where rust destroys cutting edges within months.

Point Design

135° split points self-center and prevent walking on hard surfaces. Pilot points excel in wood for clean entry holes. Standard 118° points require center punching and struggle on steel. For budget sets, prioritize 135° split points as the most versatile design.

Shank Type

Three-flats shanks grip tighter in drill chucks than round shanks, preventing slippage under load. This feature costs pennies to manufacture but separates reliable sets from frustrating ones. Hex shanks work in impact drivers but limit compatibility with standard drill chucks.

Piece Count Strategy

14-21 piece sets cover essential sizes without filler bits you'll never use. Larger sets seem economical but often include duplicate sizes and low-quality accessories. Focus on quality over quantity—five sharp bits beat fifty dull ones every time.

Case Quality

Metal cases protect bits from moisture and impact damage better than plastic. Look for secure latches and labeled size slots that keep bits organized. Poor cases lead to lost bits and rust, negating any initial savings from budget purchases.

Brand Reliability

DEWALT, Bosch, and Milwaukee maintain quality control even on budget lines. Off-brands cut corners on heat treatment and material grade. When bits cost under $25, brand reputation indicates which manufacturers still invest in proper metallurgy and quality control.

Our Testing Process

How We Test Fasteners and Hardware

🔩
Metal Drilling Test
Drilled 50 holes through 1/8" mild steel plate, measuring bit wear and cutting speed degradation. Cobalt bits tested on stainless steel to verify premium claims.
🪵
Wood Drilling Test
Bored 100 holes in oak and pine, checking for splintering, heat buildup, and edge retention. Pilot point designs evaluated for clean entry holes without brad points.
♨️
Wear Resistance Test
Ran bits continuously in abrasive MDF until dull, measuring total holes drilled. Coated bits compared against uncoated to quantify lifespan improvements from surface treatments.
🔧
Shank Grip Test
Applied side load to bits in drill chucks to measure slippage. Three-flats shanks tested against round shanks under maximum torque conditions to verify anti-slip claims.
📦
Case Durability Test
Dropped loaded cases from 6 feet onto concrete, then submerged in water to check moisture resistance. Latches cycled 100 times to simulate years of job site use.
⚡
Speed Test
Timed identical drilling tasks across all sets, measuring how quickly bits cut through standardized material samples. Faster cutting indicates sharper factory grinds and better metallurgy.
Frequently Asked Questions

Fasteners and Hardware — FAQ

What’s the real difference between titanium and black oxide coatings?
Titanium nitride adds a gold-colored ceramic layer that reduces friction and lasts 3-6x longer than uncoated bits. Black oxide is a surface treatment that prevents rust but offers minimal wear improvement. For heavy use, titanium justifies the small price premium.
Can these sub-$25 bits actually drill stainless steel?
Only cobalt M42 bits like the Bosch CO14B can handle stainless without immediate dulling. Standard HSS bits, even titanium-coated, will dull after 1-2 holes. For occasional stainless work, cobalt is mandatory—regular bits just burn up and create work-hardening.
What does 135° split point mean and why does it matter?
The 135° angle creates a sharper tip that bites into metal without a center punch. Split point designs have a small groove that eliminates walking on smooth surfaces. This feature transforms frustrating drilling into one-shot accuracy, especially critical on hardened materials.
How many drill bits do I really need in a set?
Fourteen quality bits covering 1/16" to 1/2" in 1/64" increments handle 95% of tasks. Larger sets add sizes you'll use twice a decade. Invest in a quality 14-21 piece set rather than a cheap 100-piece collection full of filler and duplicates.
What’s the best shank type for preventing slippage?
Three-flats shanks grip tighter than round shanks in standard drill chucks. Hex shanks work in impact drivers but may not fit all drill chucks. For general use, three-flats offers the best anti-slip performance while maintaining universal compatibility.
Are Amazon Basics drill bits worth buying?
The 100-piece set wins on sheer variety for occasional home use, but metallurgy can't match DEWALT or Milwaukee. Bits dull faster and run hotter. If you drill monthly, it's adequate. For weekly use, invest in name-brand sets that maintain edges longer and safer.
Final Verdict

🏆 Bottom Line

The DEWALT DWA1184 delivers professional performance under $25 with its slip-resistant three-flats shank and self-centering split point design that outperforms sets costing twice as much.

DIYers drilling weekly should grab the DWA1184; occasional users can save with the Amazon Basics 100-piece, while metalworkers must invest in the Bosch cobalt set for stainless steel work.
