M35 and the split point enable the drill bits to last longer and cut faster than the ones with standard points.
S & D Drill, Gold and black color
M35 (H.S.S. + 5% Cobalt)
M35 (HSS + 5% Cobalt) offers exceptional durability and performance for demanding applications. The cobalt addition enhances heat resistance, allowing higher cutting speeds and prolonged tool life. It maintains sharpness and hardness, even in tough materials like stainless steel. M35 is versatile, suitable for drilling, milling, and cutting tasks, delivering precision and reliability. Its toughness minimizes chipping and wear, making it a cost-effective choice for heavy-duty machining.

Benefits
-
135° Split Point
Reduces the need for excessive coolant
The 135° angle and split point design of M35 drill bits enable faster penetration into harder materials while reducing the pressure needed for cutting. This enhances chip evacuation, allowing coolant to flow more effectively to the cutting edge, optimizing performance and coolant effectiveness. As a result, less coolant is needed with the 135° Split Point compared to standard (118°) HSS drill bits.
-
135° Split Point
Eliminates Need for Center drill
The 135° Split Point design creates a self-centering effect, reducing the need for pilot holes and improving hole location accuracy. The flatter point angle of 135° (compared to the standard 118°)provides a more stable initial contact with the workpiece surface. The split point design creates four cutting edges instead of the typical two found on standard drill bits5. These additional cutting edges help distribute the cutting forces more evenly, reducing the tendency for the drill to wander.

3 Flat Shank Design
Superior grip, stability, and torque resistance
Three-flat shank drill bits provide superior grip and stability in the chuck, reducing slippage during high-torque operations. This design enhances durability, withstands higher torque and speed, and prevents spinning under heavy loads. Ideal for hard metals like stainless steel and titanium, it ensures accurate drilling, minimizes damage to the chuck and workpiece, and allows efficient torque transmission. The improved grip and stability make them perfect for demanding applications.

Purchased this to drill through the stainless steel kitchen sink, the process was quick and the entire work of installing water filter was done in no time.

I was able to drill 8 holes fairly easily in 3/16 or 1/4 steel. I still added lubricant often for each hole. It did not work well with my drill press — I believe it is under powered (time for a new one). I ended up using my 20v powered hand drill.

Ok, I’ve been drilling 304 stainless steel for the past two months on various projects and been buying left and right different drill bits of all sizes and brands. Knowing how asinine stainless is, I made sure to get only 135 degrees Cobalt M35 or M42 HSS bits. ALL of them died after one or two holes (with tapping fluid and annoying very low speeds) and half of them would even snap! Well this one, right off the bat cuts through 304 like real butter!! No more breaking my wrist and putting all of my weight on my hand drill!!Amazing, and I’m a hobby machinist. Don’t buy other brands, don’t waste your time or money, Accusize is my brand from now one, worth every penny even compared to other tool renown brands.

I needed to enlarge two 7/8" holes in 3/8" galvanized mild steel to 1". This is on a floating dock so I am kneeling over my work which is floating in salt water. The first hole cut great but, unsurprisingly, the bit bound as it was completing the hole. I reversed it out and it was dramatically bent right at the chuck. I put it in a vise and easily straightened it well enough to use it again. Doesn't seem like high speed steel should bend quite that easy. In either direction. It had a wobble after that and didn't cut worth a darn. But I got it through. I was using a half inch Milwaukee corded drill in low gear. Didn't seem much better than the stuff I get at Harbor Freight.

It did the job of drilling through 1/4 plate steel. Drilled 8 holes and didn't seem to slow down and dull the edges too much. So we give it a thumbs up. Oh, we used in drill press at slower speed so as not to burn the bit. Not sure how it would stand up at high speeds, too expensive to try and waste a good bit. We used a little cutting oil as well.

Drilled out my rotors easily so I could use thicker wheel studs. Looks like it will be a fine drill bit for steel. Don't know what the rotors are made of, but figured it should be some type of alloy since the brakes don't destroy them easily.

So I had my doubts for the price and it didn't cut well at first, but after a slight regrind, it held up to 1/8" hardened stainless for several holes.
