BLACK & GOLD DRILL BIT SET - 29 PIECE
Stop piecing together fractional sizes one bit at a time. This 29-Piece Black & Gold Drill Bit Set gives you every size from 1/16" through 1/2" in precise 1/64" increments, putting a complete everyday drilling range in one organized set. Built from M2 high-speed steel with a Black & Gold finish, these bits deliver dependable cutting performance and shop-ready durability for everyday drilling.
The 135° split point helps each bit start accurately with less walking, while the round straight shank across the entire set makes them easy to use in conventional drill chucks sized to grip the selected bit. With 29 commonly used fractional sizes packed into one metal indexing case, this is a practical go-to set for fabrication, maintenance, repair, production, and general shop drilling.

Applications & Performance
- General-purpose drilling in mild and low-carbon steel
- Sheet metal drilling with proper work support
- Aluminum drilling with appropriate speed, feed, and chip clearance
- PVC drilling where heat is controlled
- MDF drilling with proper backing and dust control
- Oak and maple drilling with support at the exit surface
- Fabrication, maintenance, production, repair, and general shop drilling
- Applications requiring closely spaced fractional sizes from 1/16" through 1/2"
The 135° split point helps establish the hole with less starting wander, while proper alignment, controlled feed pressure, appropriate drilling speed, and regular chip clearance help maintain consistent performance. The complete 1/64" size progression gives you the flexibility to select the correct fractional diameter instead of jumping to the nearest available size.

Machine Compatibility
This 29-piece set uses round straight shanks across the full 1/16"–1/2" range. Use a conventional drill or drill press with a chuck that securely grips the selected shank. Use rotary drilling mode and select speed and feed for the material and bit diameter. Confirm the machine’s drilling capacity for the material and its available speed range; chuck fit alone does not establish suitability for every application.
Compatible examples include:
-
RIKON® 30-212VS Drill Press
-
WEN® 4214T Drill Press
-
Grizzly® G7943 Drill Press
-
Grizzly® G7942 Drill Press
-
Makita® XFD13Z Drill/Driver — use when the installed chuck securely grips the selected round shank
-
Milwaukee® 3403-20 Drill/Driver — use when the installed chuck securely grips the selected round shank
-
Milwaukee® 3404-20 Hammer Drill/Driver — use when the installed chuck securely grips the selected round shank; select drilling-only mode
-
DEWALT® DCD800B Drill/Driver — use when the installed chuck securely grips the selected round shank
-
Bosch® GSR18V-400 Drill/Driver — for supported metal drilling sizes through 3/8"; verify chuck grip for the selected bit
-
Bosch® GSR12V-300 Drill/Driver — for sizes through 3/8"; verify chuck grip for the selected bit
For machines with a 3/8" maximum chuck or documented 3/8" metal-drilling capacity, the larger bits in the set require a machine with greater capacity. Always confirm the installed chuck securely grips the selected round shank before use.
Safety Tips
- Wear appropriate eye protection when drilling.
- Secure the workpiece with suitable clamps or a vise before drilling.
- Keep loose clothing, hair, and other items away from rotating parts.
- Use rotary drilling mode and turn off hammer action on hammer drills.
- Match drilling speed and feed pressure to the material and bit diameter.
- Keep the drill aligned with the bit to reduce side loading.
- Clear chips as needed and avoid excessive heat buildup.
- Support sheet metal, wood, and plastic properly to control breakthrough.
- Confirm the chuck securely grips the selected round shank before starting.
