What Customers Are Saying

The drill bit performs well for many common drilling tasks, but may struggle with very hard or thick materials like stainless steel. Customers report the bit is great, long-lasting, and able to drill through a variety of materials with ease. However, some customers experienced issues, particularly when drilling through stainless steel, with the bit struggling or failing completely in those cases. Using cutting oil and drilling slowly is recommended to get the best results.

Nice bit, but...

Would Recommend

This bit, and several like it, were on a hook with a clearance tag for a clearance price. At the register, it rang up at full price, and I had to walk back to get a photo in order to get the clearance price. Third time I had to do that in about a month. Keep an eye on the screen as you scan. The bit works fine.

Not heavy duty

Would Not Recommend

The pilot tip started the hole in 1/8 angle iron great but only penetrated 1/64" and it was done. Zero holes drilled, cutting oil didn't help. NAPA has bits for frame and bodywork that are 100 times better on steel.

Bought it to drill a couple holes in 1/16 in. aluminum angle. With this thing I could not make a single hole, it just does not dig in, even after I made a hole with smaller diameter. Useless.

Not worth buying

Poorly constructed. Would not drill two holes in a concrete block before becoming hopelessly dull.
