Why Decimal Equivalents Matter

Machinists work in decimals, but drill bits, taps, and prints often call out fractional sizes. A quick fraction-to-decimal lookup saves time and prevents the costly mistake of grabbing a 5/16 when you needed a 19/64.

• Covers all standard fractional sizes from 1/64 through 1 inch in both decimal and metric equivalents
• Essential for selecting the nearest drill size when a specific decimal diameter is needed
• Pairs with letter and number drill sizes for complete drill selection coverage
