Best 0.020-Inch Drill Bits for Precision Crafting and Small Projects
A 0.020-inch drill bit is useful for making very small holes in detailed craft, jewelry, model-making, and repair work. The GYROS #76 set is a direct match for buyers who need multiple bits at exactly 0.020 inch; HARFINGTON also lists bits at 0.020 inch, while the Biaungdo #61–80 set includes that size alongside finer options. For a broader metric range, choose Biaungdo’s 20-piece set. Buyers who want a manual holder and bits together can consider the 21-piece kit.

|---|---|---|
| GYROS #76 Set | Multiple bits at 0.020 inch | #76, 0.020 inch |
| HARFINGTON #75 Bits | HSS bits listed at 0.020 inch | 0.5 mm / 0.020 inch |
| Biaungdo #61–80 Set | Wire-gauge size selection | Includes #76, 0.020 inch |

GYROS #76 Micro Drill Bit Set
The GYROS set contains 12 carbon-steel twist drill bits, all listed as size #76, or 0.0200 inch (0.508 mm). Having several bits of the same size can be useful for repeat work or as replacements when a very small bit is damaged. The listing describes the bits as suitable for jewelry, plastic, resin, and soft metal, and notes that they have straight shanks for compatible tool-holding systems.
Best for: Makers who need several bits at the exact #76 size for precise craft or hobby drilling. The manufacturer describes use with hand and motorized tools, but notes that some rotary tools require a mini adaptor chuck and hand drilling can use a pin vise. Limitation: This set offers one size only, so it is less versatile when a project needs different hole diameters.
HARFINGTON 0.5 mm HSS Drill Bits
HARFINGTON supplies 12 jobber-style twist bits listed as 0.5 mm (0.020 inch), with a 20 mm overall length and a stated drilling depth of 5 mm. The bits are made from 6542 high-speed steel. The product description says the straight shank is designed for chucking in standard drill machines and identifies stainless steel, aluminum, wood, and plastic as intended materials.
Best for: Buyers who want a batch of HSS bits identified by metric diameter and need a stated drilling depth. It is a straightforward choice when the project calls for a 0.5 mm bit. Limitation: The set provides the same listed diameter rather than a range, and the stated 5 mm drilling depth is a practical constraint for deeper holes.
Biaungdo #61–80 Micro Bit Set
This 20-piece HSS set covers wire-gauge sizes #61 through #80. Its listed sizes run from #61 at 0.0390 inch down to #80 at 0.0135 inch; #76 is listed as 0.0200 inch. The range gives users several nearby options for small holes, and the listing describes the bits as intended for precision drilling, jewelry DIY, carving, and wood drilling. The maker also cites rust and corrosion resistance as material features.
Best for: Buyers who need a 0.020-inch bit but also want finer and larger wire-gauge sizes in the same set. Limitation: The smallest bits are delicate; select the correct size carefully and use a holder that securely fits the shank. The product details do not specify a dedicated storage case.
Biaungdo 20-Piece Metric Bit Set
This set contains 20 fully ground HSS twist drills in metric sizes from 0.3 mm to 1.5 mm, with several intermediate diameters. The listed assortment includes a 0.5 mm bit, which is approximately 0.020 inch. The range is useful when a project requires stepping between hole sizes rather than repeatedly using only one diameter. The listing highlights rust and corrosion resistance and describes the bits for rotary and hand-tool DIY use.
Best for: Crafters who work from metric measurements or need a compact range for detailed projects. Limitation: It is not a single-size 0.020-inch set; check the metric marking and choose the 0.5 mm bit when that is the required diameter.
Metric Micro Bits with Pin Vise
This kit combines 20 high-speed-steel twist bits with a manual pin vise. The listing gives a 0.3–1.6 mm holding range for the three-claw keyless chuck and describes the vise as 9.4 cm (3.7 inches) long with a slip-resistant grip. The bit assortment is presented for jewelry making, model building, beads, and detailed DIY work. Because 0.5 mm is approximately 0.020 inch, confirm that the supplied assortment includes the diameter required before purchase.
Best for: Buyers who prefer controlled hand drilling and want a vise and small-bit assortment together. Limitation: The provided product details do not enumerate every bit diameter, so they do not confirm an exact 0.5 mm bit in the set.
Buying Guide: Choosing a 0.020-Inch Drill Bit
Is 0.020 inch the same as 0.5 mm?
They are close but not exactly identical: 0.020 inch converts to 0.508 mm, while 0.5 mm converts to about 0.0197 inch. For many small craft tasks, the difference may be acceptable, but precision work should follow the project’s specified measurement. A #76 bit is listed as 0.020 inch in the GYROS and Biaungdo wire-gauge product details.
Should you buy one size or an assortment?
Choose a single-size set such as GYROS when repeat holes at #76 are the priority. A wire-gauge or metric assortment is more flexible for projects that require multiple diameters. Before buying, check whether the listing gives exact sizes or only a range.
What material and tool details should you check?
Compare the stated bit material, intended work materials, shank style, and tool-holder requirements. HSS is listed for the Biaungdo and HARFINGTON options; GYROS uses carbon steel. Tiny bits need secure holding and careful handling. Follow the tool maker’s instructions, and avoid forcing a bit if it binds.
