Description of Chicago Latrobe High Speed Conventional 26 Piece
Set of 26 short length drill bits includes one each of letter sizes A through Z. High-speed steel (HSS) provides hardness for wear resistance. Uncoated (bright) finish is an untreated surface that can be used on a range of materials, especially soft metals. 118-degree conventional point for a range of drilling applications. Short length drill bits have the strength and rigidity required for heavy-feed rate applications. Made in the USA.
I work a lot with aluminum and mild steel and find that short drill bits are preferred for most applications. These letter sizes fill in the in-between sizes between part drills well and often allow for better tapping. I mostly use them with a drill press. The tips are well polished with no chips or offsets from the center. Good product at a good price.
