Key Features
Lot of 10 Hanson high-speed steel fractional drill bits
Silver & Deming-style large-diameter twist drills
Sizes range from 17/32 inch through 1 inch
Hanson part numbers 91134 through 91164 as listed
Reduced-shank configuration for accepting larger-diameter bits in smaller chucks
Three-flat shank areas visible on the bits for improved chuck grip
Approximately 6-inch commercial-length configuration
Original labeled yellow Hanson tube and green tube section for each bit
Hanson and USA markings visible
Suitable for machinists, fabricators, mechanics, restoration shops, and collectors
Selected assortment rather than a complete sequential drill index
Current versions carrying these same Series 911 part numbers are described as 6-inch Silver & Deming drills with 1/2-inch reduced, three-flat shanks and conventional 118-degree points.
Manufacturer Background
The Henry L. Hanson Company operated in Worcester, Massachusetts and was known for high-speed drills, taps, dies, screw extractors, and related cutting tools. A surviving 1969 company catalog documents Hanson’s high-speed steel Silver & Deming drill line for creating larger holes with reduced-shank drills. Hanson later became associated with the Irwin tool organization, and the same basic 911-series part numbers continued under Irwin/Hanson branding.
Country of manufacture: United States, based on the USA markings visible on the drill bits.
Estimated Age
Likely manufacture period: approximately 1975 through 1985, or about 41–51 years old in 2026.
Note: This is an informed estimate rather than a factory-confirmed production date. Hanson’s 1969 catalog used earlier 901-series numbers and listed a Worcester 01608 address, while these tubes carry later 911-series numbers and Worcester 01606. A company-history source reports that Hanson moved to another Worcester facility in 1975, while secondary tool-history research places the Irwin acquisition around 1985. The standalone Hanson packaging therefore most plausibly dates from the late 1970s to mid-1980s.
