Drill bit STANLEY STA52190 — 8 mm x 200 mm, twist drill for metal/wood

STANLEY STA52190 — 8 mm x 200 mm twist drill is a general-purpose drill bit designed for drilling in metal and wood. This single 8 mm diameter, 200 mm long bit offers extended reach for deeper holes while remaining compatible with common handheld drills and drill presses. The straight shank and twist geometry provide reliable chip removal and a stable drilling action for routine repair, construction and workshop tasks.

Advantages

The long 200 mm length enables drilling through thicker sections or creating deep pilot holes without changing to extension accessories. Its 8 mm diameter is a common size for bolts and fasteners, allowing precise fit for through-holes. The twist design facilitates efficient cutting and evacuation of chips in both wood and metal, while the standard shank ensures easy fitting into most chucks. The single-piece supply simplifies inventory and selection for occasional or professional users.

How to use

Secure the drill bit in the chuck of the drill or drill press, ensuring it is centered and tightened. Select an appropriate speed and feed rate for the material—lower speeds for metal, higher speeds for softer wood—and apply steady pressure while allowing the bit to cut without forcing. For deeper holes, periodically retract the bit to clear chips and reduce heat buildup. Use cutting fluid or lubricant when drilling metal to extend bit life and improve finish.

Usage recommendations

For best results, match drill speed and feed to the material, clamp workpieces securely, and use coolant when drilling metal. Inspect the bit for wear before use and replace when dull to maintain hole quality and reduce the risk of breakage.
