About Drill America - KFDRSD3/4 3/4" Reduced Shank High Speed Steel Black & Gold KFD Drill Bit
Overall Feedback:
82% positive
72% praised for its fast drilling speed, while 28% found it slow
After drilling one hole, my drill bit dulled and lost its edge. It did not perform well for drilling 10 holes in axles.
78% liked its long-lasting durability, but 22% experienced frequent breakage
I have experienced severe chattering in all three tools while using them as the bit would not stay tight in the chuck for more than a minute or so.
I found that the drill bit lost its edge after drilling just two holes and was not durable enough for drilling 10 holes in axles.
77% liked the comfortable grip design
The product's superior strength rivals many top brands for less money.
69% found it resistant to heat buildup, but 31% experienced thermal damage
I was drilling at a slow speed and using cutting fluid to prevent the bit from getting hot.
I had to use both drill bits to drill one hole because they were dull.
74% praised for its versatility in drilling various materials, though 26% had difficulty with metal
I have bought jobber-drill-bits made of nicer tool steel than some on Amazon and at big box stores.
I suggest that the drill bit is suitable for wood or softer materials like Aluminum but not for harder materials.
