The device of claim 7 wherein an inner wall of said double collet member engages a tip portion of said tool bit, maintaining a position of said tool bit when said tool bit is forcibly disposed inside said inner recess of said double collet member, said inner wall being perpendicular to a longitudinal axis of said double collet member. 9. The device of claim 1 wherein said second end portion of said double collet member includes a plurality of gripping arms extending from a mid-portion of said double collet member. 10. The device of claim 9 wherein said gripping arms include: a) outer arcuate walls dimensioned to provide an outer cylindrical periphery configured to promote insertion into said collet retention cap; and b) inner arcuate walls that cooperate to grasp said drill bit such that rotary motion is transferred from said first end portion of said double collet member to said drill bit, said inner arcuate walls having a radial dimension substantially equal to the radial dimension of said drill bit. 11. The device of claim 10 wherein said gripping arms extend parallel to a longitudinal axis of said double collet member. 12. The device of claim 10 wherein said inner arcuate walls of said gripping arms include: a) an angled portion that forms an acute angle with said outer arcuate walls of said gripping arms thereby promoting the insertion of said securing end of said drill bit into said second end portion of said double collet member; and b) a straight portion that extends parallel to said outer arcuate walls of said gripping arms thereby promoting grasping of said securing end of said drill bit to transfer rotary motion from said double collet member to said drill bit. 13. The device of claim 12 wherein said inner portion of said collet retention cap defines a frusto-conically configured inner recess when taking a side sectional elevation view of said collet retention cap. 14. The device of claim 13 wherein said collet retention cap includes a cylindrically configured outer portion having a threaded cylindrical inner wall that promotes the rotational joining of said collet retention cap to said threaded outer wall of said second end of said adapter hex member. 15. The device of claim 14 wherein said rotational joining of said collet retention cap to said adapter hex member forcibly urges said inner arcuate walls of said gripping arms into congruent engagement with said securing end of said drill bit thereby promoting the transfer of rotary motion to said securing end of said drill bit, said forcible urging of said inner arcuate walls of said gripping arms against said securing end of said drill bit occurring after said second end portion of said double collet member is disposed inside said inner recess of said collet retention cap, and after said securing end of said drill bit is disposed inside said second end portion of said double collet member. 16.
