Drafted tool bit

PARZYNSKI JR DAVID B / CONGDON THOMAS M

A tool bit (200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000) comprises a shank portion (202, 302, 402, 502, 602, 702, 802, 902, 1002, 2002) defining a longitudinal axis (L), and a working portion (204, 304, 404, 504, 604, 704, 804, 904, 1004, 2004) extending downwardly axially from the shank portion (202, 302, 402, 502, 602, 702, 802, 902, 1002, 2002). The working portion (204, 304, 404, 504, 604, 704, 804, 904, 1004, 2004) includes a rear region (616, 716, 816, 916, 1016, 2016), a front working region (605, 705, 805, 905, 1005, 2005), a first side region (618, 718, 818, 918, 1018, 2018) and a second side region (620, 720, 820, 920, 1020, 2020), and the first side region (618, 718, 818, 918, 1018, 2018) and the second side region (620, 720, 820, 920, 1020, 2020) define an angle of extension (? ) measured in a plane perpendicular to the longitudinal axis (γ), forming a wider front working region (605, 705, 805, 905, 1005, 2005) than the rear region (616, 716, 816, 916, 1016, 2016) in a plane perpendicular to the longitudinal axis (L).
