13-Piece Jobber Length Drill Bit Set
This set contains thirteen high-speed steel drill bits with a 118-degree point angle designed for general-purpose drilling tasks. The black oxide finish provides corrosion resistance and reduces friction during use. It is suited for mechanics, fabricators and DIY users who need a range of standard jobber-length bits in one package. The model number is 57729.
Capacity and headroom for thirteen bits
The thirteen pieces cover a spread of diameters that handle common pilot, clearance and tapping holes in metal, wood and plastic. High-speed steel construction withstands the heat of repeated drilling in mild steel and aluminium. The set runs out when a project requires sizes outside the included range, specialised coatings for abrasive materials or longer bits for deep-hole work.
Practical limits of the 118-degree point
The 118-degree point angle centres easily without a pilot hole and performs well in softer metals and wood. In harder alloys or stainless steel the wider angle can wander and generates more heat, slowing progress and reducing bit life. The black oxide finish helps chip flow but does not replace cutting fluid for tough materials or high-speed production drilling.

Questions about this item
Will the 13-piece set cover the same diameters as my existing fractional drill index?
The set contains 13 jobber-length bits with a 118-degree point angle made from high-speed steel; compare the size markings on your current index to the sizes included in this pack.
How can I verify the 118-degree point angle is correct on each bit after unpacking?
Use a drill-point gauge or protractor to measure the cutting edges; each bit should show a 118-degree included angle and a black-oxide finish.
Does the 57729 package include a storage case or only the 13 black-oxide bits?
The box holds the 13 high-speed steel jobber-length bits; no separate case or accessories are mentioned.
