Collection: 5-Packs of Carbide Drill Bits by Size

```html

Shop 5-packs of factory resharpened solid carbide drill bits by individual size. Each product listing below is for one specific drill diameter, and each pack contains five drills of that same size.

These precision micro drills provide an economical way to keep multiple drills of a frequently used size on hand. They are suitable for PCB drilling, CNC work, electronics, plastics, composites, brass, aluminum, model making, and other precision small-hole applications.

What Each Product Includes

• 5 carbide drills per pack
• All 5 drills are the same diameter shown in that product listing
• Factory resharpened solid carbide drills
• Standard 1/8" shank (3.175 mm)
• 1.50" overall length
• Flute length varies by drill diameter
• Colored depth-stop rings included; ring color may vary

Factory Resharpened Carbide Value

These drills have been professionally factory resharpened to restore the cutting edges and provide reliable precision performance at a lower cost than comparable new carbide drills. Factory resharpened tooling is a practical choice for production work, repeated drilling, prototyping, and applications where keeping spare drills available is important.

Because these are resharpened tools, minor cosmetic differences and slight flute-length variation may occur. The listed cutting diameter and standard 1/8" shank remain the key ordering specifications.

Why Buy 5 Drills of the Same Size?

• Keep Backup Drills Available
  Small carbide drills are precise but brittle, so having several drills of the same diameter can reduce downtime if one breaks or wears.
• Lower Cost Per Drill
  Five-piece packs offer an economical quantity for commonly used sizes.
• Consistent Diameter
  Each product is a one-size pack rather than an assortment of different drill sizes.
• Useful for Repeated Work
  A five-pack is convenient for production runs, repair work, recurring hole sizes, and frequently repeated jobs.

Common Applications

• PCB and circuit-board drilling
• CNC and precision small-hole drilling
• Electronics prototyping and repair
• Plastics, acrylics, fiberglass, and composites
• Brass, aluminum, copper, and other suitable non-ferrous materials
• Model making, hobby work, and detailed fabrication
• Repeated drilling where several tools of the same diameter are useful

Important Use Notes

• Solid carbide drills are hard and accurate but also brittle.
• Use a stable drill press, CNC machine, milling machine, PCB drill holder, or other controlled setup.
• Avoid handheld electric drills, bending, side-loading, or forcing the drill.
• Secure the workpiece and keep the drill properly aligned.
• Use appropriate feeds, speeds, depth of cut, and chip clearing for the material being drilled.
• For the smallest diameters, minimize runout and use especially light feed pressure.
