CREATE TABLE table_204_828 (id NUMBER, "whitworth size  ( in ) " NUMBER, "core diameter  ( in ) " NUMBER, "threads per inch" NUMBER, "pitch  ( in ) " NUMBER, "tapping drill size" CLOB)

SELECT "whitworth size (in)" FROM table_204_828 WHERE "tapping drill size" = 'number drill 26 (3.7 mm)'
SELECT "whitworth size (in)" FROM "table_204_828" WHERE "tapping drill size" = 'number drill 26 (3.7 mm)'
