Drill America Z High Speed Steel KFD Split Point Drill Bit Pack of 6

In this review of the Drill America Z High Speed Steel KFD Split Point drill bit pack, the bottom line is clear: this set is built for general purpose work that demands a balance of hardness and toughness. Our review finds these jobber length bits particularly useful for users who need reliable performance drilling through wood, mild steel and even stainless with a gold and black surface treatment that helps resist wear. The heaviest selling point is the 135 degree split point tip, which reduces walking and makes placement easier for both handheld and benchtop drilling.

Key Features

• Premium HSS construction: Manufactured from high-speed steel for a combination of hardness and toughness that supports general purpose drilling and wear resistance.
• 135 degree split point tip: Self-centers and reduces thrust so the bit starts cleanly without wandering on startup.
• Gold and black surface treatment: Surface treated to improve performance when cutting hard metals like stainless and to extend tool life.
• Jobber length design: Standard jobber length gives versatile reach for common shop and jobsite tasks without excess flex.
• Round shank compatibility: Round shanks allow use with a wide variety of chucks and toolholding systems for convenience.
• Right-hand cut flutes: Spiral flutes evacuate chips up and out of the hole to reduce clogging during drilling.

Who It's For

This pack is aimed at hobbyists, home mechanics and tradespeople who need an affordable set of versatile drill bits for wood, general steel and occasional stainless work. The self-centering split point and HSS construction make it suitable for tasks where accuracy and bit life matter but carbide or cobalt tools would be overkill.

Those who need heavy production duty or extreme longevity in abrasive materials should look elsewhere at specialty cobalt or carbide options, since some customers report mixed durability under very high use or abuse. For routine shop use and intermittent stainless drilling, this set offers good value.

Pros & Cons
