Description of πŸ”§ COMOWARE 9/16-Inch

High Quality Material - High Speed Steel M2 Black and Gold, resists corrosion, ensures outstanding durability, sharpness and capability, reduces the friction and runs cooler. Black and Gold Oxide Finish - Premium gold titanium and black nitride dual coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface. 135-degree & Split Point - Increases cutting speed with self-centering and prevents walking, clears chips and particles faster. The split point tip can increase the wear resistance. 135-degree penetrates hard material without a pilot hole and produces small chips to reduce clogging. Special Design - Unique tri-flat shank and 1/2” reduced shank can lock onto chuck to permit portable drilling. The special design can drill tough and high-tensile strength materials. The bit is only suitable for portable drilling with 1 / 2 "drill chuck,not applicable to other drill chuck sizes. General Purpose - It is ideal for drilling steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon and composite materials.

Fantastic Drill Bit

The COMOWARE 9/16" industrial drill bit is fantastic. Based on my observations, it can cut through tough material with ease and precision. The flutes are designed to remove chips and debris quickly, reducing heat build-up and making the drilling process smoother. The material used is high-quality and durable, ensuring long-lasting use. The only con I have noticed is that it can be a bit pricey compared to other brands.

Pros
  • Strong and durable construction for long-lasting use.
Cons
  • Might not fit certain types of machines or devices that require a different size wrench.

Looks like a nice sharp drill bit πŸ‘

Looks like an excellent quality drill bit. I hope this makes the large turning operations on the lathe easier. So far the largest twist drill bit I've had has been a 1/2 inch. It's a big pain to work your way up with bigger and bigger drill rods to open a tiny 1/2 inch hole lol. I'm sure it will save me a lot of time.

Pros
  • General Purpose - Ideal for drilling steel, copper, aluminium, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon and composites.
Cons
  • Expensive

Received broken in half. No delivery problem.

When I receive a damaged product, it is usually due to a delivery problem. This one confused me. The packaging it came in was perfect, as was the original packaging that can be seen in photo 1. Somehow my new 5/8 heavy duty drill broke in half. See Figure 2. If you put the two pieces together, you can clearly see that there are no large pieces missing in the area where the crack occurred. However, these fragments are nowhere to be found. I can only assume that the packaging was damaged through…

Pros
  • 135 Degrees and Split Point - Increases cutting speed with self-centering and eliminates movement, removing chips and particles faster. Split tip can improve wear resistance. 135 degrees penetrates hard material without a pilot hole and creates fine chips to reduce clogging.
Cons
  • I don't remember
