LICHAMP Double Fluted Step Drill Bit for Cutting Metal Hole 19 Sizes from 3/16 to 1-3/8 inch, Genuine M35 High Speed Steel

Decided to install a soap pump in my stainless sink but lacked a hole for it. This bit did a great job and left a clean cut. Don’t forget the milling oil to help preserve the bit.

This is a bargain, it is made of good steel, it has the starter bit on the tip, and works well on a drill, It is not the same quality as the Milwaukee or Klien but still nice. It is a fraction of the cost.

Very versatile tool for making different size holes in different materials. I used it on wood and aluminum sheets. It is a little tough to figure out what size hole you're making and I found myself checking and rechecking the hole diameter frequently. Also, it is tough to punch a hole of specific diameter in thicker wood. The shape of the head causes the hole to be funnel shape, so if you want a clean hole of uniform diameter through the entire sheet, there is some additional work involved. But it does the job!

I started a project using the cheaper COMOWARE bit - but it got stuck in the thin material I was working on. The problem was that I had to hand hold the drill for my project while drilling thin aluminum in my trailer. The cheaper bit actually got lodged in the material. So I ordered the LICHAMP Double Fluted Step Drill Bit, What a difference! I could drill holes using my hand drill much faster without fear of getting the bit stuck or buckling the material. Smaller step sizes and a sharper bit made the difference. Under the right circumstances, it actually cuts like butter. If you have a more challenging project you can't go wrong with a bit like this. Recommended!

I use this all the time at work & it’s still holding up. Highly recommended by an electrician!

Been using for trailer rebuild and has gotten a pretty good work out opening up holes in 1/4" solid steel. Glad I got it, has saved the day by letting me open up holes larger than my drill bits go and is working great as a deburring tool. Will definitely buy this again, if it ever wears out! Cool beans!

good for the first few cuts.... after that you can tell where it came from

Good

J ai acheté cela pour faire un trou dans une tole chez moi. J ai trouvé que ca a percé très rapidement et proprement. Après cela elle avait l air comme neuve. En partant, c était 5/5. On a eu une demande urgente à l usine afin de percer 2 trous de 1-1/4 dans une plaque de 1/16 de stainless 304. Ne trouvant pas de forêt aussi gros dans les quicailleries, on a tenté d utiliser mon ptit foret d amazon..réellement désespéré. C était effrayant de commencer une job sans etre sûr de la finir. Et bien en poussant en masse à base vitesse, avec beaucoup d huile de coupe, elle a mangé dans le stainless en 3-4 min. Les copeaux de stainless se generaient bien. Tellement beau à voir. Elle a fait le 2e trous aussi rapidement que le 1er. Je ne suis pas expert, mais même à la fin elle semblait en bonne etat. Wow.

The media could not be loaded. J'ai agrandi 4 trous du diamètre ¾ de pouce jusqu'à 1po ⅛ sur de l'acier ⁵/32 d'épaisseur et le forêt est toujours coupant et en bon état. Très impressionné de la qualité pour ce prix.

Semble de bonne qualité.

Je suis super satisfait utilisation commerciale tout les jours

Works good for an electrician, 1/2" 3/4" && 1"Has held up good for 20 holes so far.
