29-piece HSS jobber drill set
The Westward 4UM92 set contains 29 high-speed steel jobber drill bits with a 118-degree point angle and black oxide finish. It is suited for general-purpose drilling in metal, wood and plastic where a standard jobber length is appropriate. The set provides a range of common sizes for workshop or maintenance tasks.
Practical limits of 118-degree HSS bits
The 118-degree point is designed for general-purpose drilling and works well in mild steel, aluminium and non-ferrous materials. High-speed steel retains hardness at moderate temperatures but will wear faster in hardened steel or high-temperature alloys. Black oxide finish aids chip flow and provides some corrosion resistance.
Check your chuck capacity and material needs
Verify that your drill chuck can accommodate the largest bit diameter you intend to use from the set. Confirm the workpiece material is compatible with standard HSS 118-degree geometry; hardened or abrasive materials may require cobalt or carbide tooling instead. California Proposition 65 warnings apply to this product.

Questions about this item
Which drill-bit set should I pick if I need the 29-piece jobber-length option?
This Westward 4UM92 set contains exactly 29 high-speed-steel jobber drills with a 118-degree point and black-oxide finish, covering the standard fractional range in one case.
What does the 118-degree point angle mean when I start drilling?
The 118-degree point is a general-purpose geometry that centres easily in steel, aluminium and plastic without a pilot hole and gives good chip clearance at normal hand-drill speeds.
How does the black-oxide finish affect performance on a jobber-length bit?
Black oxide reduces galling and improves lubricity so the 118-degree HSS cutting edges stay cooler and resist wear longer in repetitive drilling.
