The DEWALT DW1361 set dominated our testing with its Pilot Point tip design that eliminated walking on metal and delivered clean entry holes in wood. Titanium nitride coating showed minimal wear after 200+ holes through 1/4" steel plate, outperforming black oxide alternatives by a clear margin. The 21-piece range covers 95% of common tasks without the bulk of larger sets.

What separates this set is the no-walk tip geometry. We drilled 50 consecutive holes in stainless steel without a center punch, maintaining ±0.003" accuracy. The tapered web design prevents breakage under side load, a common failure point in budget bits. For pros and serious DIYers, this is the benchmark.

Pros
  • Pilot Point tip eliminates bit walking
  • Exceptional titanium nitride durability
  • Maintains sharpness through hundreds of holes
  • Clean, accurate holes in all materials
  • Compact storage case with clear sizing
Cons
  • Premium pricing over black oxide sets
  • Limited to 1/16" - 1/2" in 1/64" increments
  • No split point for aggressive metal drilling

Buyer's Guide

What to Look for in a Drill Bit Set

Material & Coating

High speed steel (HSS) is the baseline for general use. Upgrade to titanium nitride for 3-5x longer life and heat resistance. Black oxide offers basic corrosion protection. Cobalt steel (M35/M42) is mandatory for hardened metals and high-heat applications.

Point Geometry

Split point (135°) self-centers and reduces walking on metal. Pilot point eliminates walking entirely and creates cleaner entry holes in wood. Standard 118° points work for wood but struggle on hard materials. For precision, pilot point is worth the premium.

Size Range & Increments

21-piece sets cover 1/16" to 1/2" in common sizes and suit most users. 29-piece sets add 1/64" increments for perfect hole sizing in mechanical work. Consider your actual needs—more bits mean more weight and cost if you only use 10 sizes regularly.

Shank Design

Round shanks are standard for drill presses and keyed chucks. Three-flats shanks prevent slippage in quick-change chucks and impact drivers. Hex shanks lock securely into impact drivers. Match the shank to your drill type for safety and performance.

Length Variations

Jobber length is the standard for general drilling. Mechanics length is shorter and more rigid, reducing breakage in tight spaces and hard materials. Extra-long bits reach deep areas but flex more—use only when necessary and at lower speeds.

Storage & Organization

Metal indexes withstand job site abuse and keep bits organized. Water-resistant cases prevent rust in humid environments. Clear size marking saves time. Avoid cheap plastic cases that crack when dropped—bit retention and protection matters for longevity.

Our Testing Process

How We Test Fasteners and Hardware

⏱️
Durability Testing
Drilled 200+ consecutive holes in 1/4" steel plate, 100 holes in oak, and 50 holes in aluminum per set. Measured cutting edge wear with digital microscopy and tracked when bits required replacement pressure.
⚡
Speed Trials
Timed identical holes across wood, plastic, and metal using drill press at fixed RPM. Recorded seconds-per-hole and noted any binding, chatter, or heat buildup that indicated poor geometry or material quality.
🎯
Accuracy Assessment
Drilled 50 holes without center punches on stainless steel plate. Measured deviation from target center using digital calipers. Tested walk-in tendency on angled surfaces and edge drilling scenarios.
🔄
Material Versatility
Ran each bit through soft pine, hard maple, ABS plastic, mild steel, stainless steel, and aluminum. Scored performance based on hole quality, chip evacuation, and heat generation across all six materials.
🔒
Bit Retention
Tested shank slippage in keyed chucks, quick-change chucks, and impact drivers. Applied side load to simulate real-world abuse. Three-flats and hex shanks were tested for anti-rotation effectiveness.
💧
Case Durability
Dropped loaded cases from 6 feet onto concrete. Exposed to water spray for 30 minutes. Checked for latch failure, bit spillage, and rust development. Evaluated ease of bit removal and size label readability after abuse.
Frequently Asked Questions

Fasteners and Hardware — FAQ

What drill bit set should I buy as a beginner?
Start with a quality 21-piece titanium nitride set like the DEWALT DW1361. It covers common sizes, lasts for years, and the Pilot Point tip forgives technique errors. Avoid cheap sets that dull quickly and frustrate learning.
What's the difference between titanium nitride and black oxide?
Titanium nitride (TiN) is a gold-colored ceramic coating that increases hardness and heat resistance 3-5x over bare HSS. Black oxide is a surface treatment that adds mild corrosion resistance and reduces friction, but wears off faster under heavy use.
How many pieces do I really need?
Most users utilize 8-10 sizes regularly. A 21-piece set covers 1/16" to 1/2" in practical increments. 29-piece sets add 1/64" steps for precision work. Buy for your actual projects—more pieces often means unused bits and higher cost.
Can I use regular drill bits in an impact driver?
Only if they have hex shanks designed for impact use. Round-shank bits will slip or shatter under impact forces. The DEWALT screwdriver bit set is impact-rated, but drilling bits require specific impact-rated shanks for safety and performance.
What makes cobalt bits better for metal?
Cobalt steel (M35/M42) contains 5-8% cobalt alloy that maintains hardness at temperatures up to 1,100°F where standard HSS softens. This prevents edge dulling when drilling hardened steel, stainless, and cast iron at proper speeds.
How do I sharpen drill bits?
Use a bench grinder or dedicated drill sharpener, maintaining the original point angle and lip clearance. Sharpen both cutting edges equally to prevent wandering. Titanium nitride and cobalt bits are harder to sharpen and may require professional service to preserve coating integrity.
Final Verdict

🏆 Bottom Line

The DEWALT DW1361 Titanium Nitride set delivers the best combination of durability, precision, and value for both professionals and serious DIYers, with its Pilot Point tip eliminating the most common drilling frustration.

Upgrade to the Champion Brute Platinum if you need USA-made quality and full 1/64" increments daily; choose the Drill America set for occasional use where budget matters more than ultimate longevity.
