Chicago-Latrobe 69901 Bit Set

The Chicago-Latrobe 69901 set delivers 26 screw-machine drill bits covering letter sizes A through Z. High-speed steel construction suits general-purpose drilling in metal, wood and plastic. Mechanics, fabricators and maintenance crews gain a complete letter-range kit in one package.

118-degree point under load

The 118-degree conventional point centres quickly and resists walking when pressure is sustained. Bright uncoated flutes clear chips steadily during extended drilling cycles. High-speed steel retains hardness so cutting edges stay sharp through repeated holes.

Letter-size limits

Letter sizing stops at Z, so holes larger than the maximum letter diameter need a different system. Bright finish offers no heat-barrier coating for high-speed production runs. Conventional point geometry is not optimised for hardened alloys or deep-hole work.

Questions about this item

Will the high-speed steel bits generate excessive heat during continuous drilling?

The 118-degree conventional point on each high-speed steel bit is designed for efficient chip removal, which helps control heat buildup during extended use.

What type of drill chuck is required to hold these letter-sized bits?

The set includes 26 letter-sized bits from A through Z, so you need a drill with a chuck capacity that accommodates the largest bit in the range.

Can these bright-finish bits be used effectively in older drill presses with lower spindle speeds?

Yes, the high-speed steel construction and 118-degree point angle are well-suited for conventional drilling machines operating at standard speeds.
