Accuracy & Longevity - 135 degree split point starts drilling immediately requires less force and eliminates “walking” across the working surface. Tapered web provides strength, durability, and reduces breakage.

Three-Flat Design - Three flats on shank eliminate bit spinning in chuck. Our proprietary parabolic flute design brings optimal chip removal which reduces heat build-up.

Wide Range of Uses - Drill bits are built for general purpose applications, such as steel/copper/aluminum/zinc alloy/wood/plastics. Also, it's ideal for DIY projects and home maintenance. Durable and reliable quality.

Black gold high speed steel is the long lasting material when it comes to common drill bit materials, not only will the bit's structural integrity withstand tremendous heat and wear, but more importantly black gold bits can drill through tougher materials than common HSS bits.

With a 135 degree split-point, these drill bits will catch on the work-surface with greater ease and not wander all over the surface making scratch-marks. This means that after securing the bit in the machine all that is needed is a steady hand to point and apply pressure, and that's it.

The 3-Flat shank of our bits means you can use this drill bit with nearly all types of machines.

Long length drill bit has an extended flute and overall length to drill deeper and reach farther than a jobber length drill bit

Cobalt steel provides extended tool life compared to high-speed steel drill bits when drilling hard materials

Gold oxide finish lubricates and provides wear resistance on ferrous materials

Quantity: 1 piece | Color: Gold | Grit: Extra Fine, XF | Shank size: 3/32"

[TUNGSTEN CARBIDE] Pana 3/32” Shank Tapered Carbide Bit has a medium grit to rapidly shorten, and shape and gives you a smooth and fast backfill. This bit can remove hard gels, poly gels, acrylic, dip powders, and rhinestones safely. It is made of an exceptional tungsten steel material which will provide durability for long-lasting use without the concern of dullness. This carbide bit is corrosion resistant to high temperatures and will provide you a long-lasting use.

[SHAPE] The tapered edge of the drill bit includes a finer grit at the tip of the bit to avoid any damage to the cuticle and surrounding nail wall. A coarser grit towards the base of the bit allows for a brisk removal and sharpening of acrylic gel nails, thick extension nails, builder gel nails, and natural nails.
