Hole Drill Bit Wolfcraft 424585 HSS with Adjustable Depth Stop for Precision Drilling

Wolfcraft 424585 HSS with adjustable depth stop is a high-speed steel hole drill bit engineered for controlled, repeatable drilling in metal and wood. The tool combines an HSS cutting tip for reliable penetration with an integrated, adjustable depth limiter that ensures uniform hole depth across multiple operations. Its design supports tasks that require consistent positioning and depth accuracy, such as mounting hardware, preparing components for fasteners, and general workshop drilling.

Advantages

The HSS construction provides good hardness and heat resistance for a range of materials while maintaining cutting edge durability. The adjustable depth stop allows precise control over drilling depth without frequent measurement, reducing rework and saving time. A straight shank and balanced geometry help maintain concentricity and reduce wobble, resulting in cleaner holes and improved fit for dowels, screws, and fittings.

Suitable for

• Drilling precise depth holes in wood for dowels and fittings
• Metalworking tasks that require short to medium depth holes
• Repeatable installation work such as mounting brackets or fixtures
• Workshop and repair jobs where consistent hole depth is important

Key specifications

• Material of cutting part: high-speed steel (HSS)
• Integrated adjustable depth stop for controlled drilling depth
• Suitable for use in wood and various metals
• Straight shank for secure chuck gripping and stable rotation
• Designed for repeatable, precision hole making

How to use

Secure the drill bit in the chuck, then set the adjustable depth stop to the required drilling depth by sliding it along the shaft and tightening the locking screw. Position the drill perpendicular to the workpiece and start at low speed to establish the hole, increasing speed as appropriate for the material. Apply steady pressure and stop once the depth stop contacts the workpiece surface. For metal work, use appropriate cutting fluid; for wood, clear chips frequently to avoid clogging.

Usage recommendations

Use appropriate safety equipment such as eye protection and gloves. For best results, select drilling speeds and feed pressure according to material hardness: lower speeds for metals with cutting fluid, moderate speeds for hardwood, and higher speeds for softwood. Inspect the cutting edge before use and replace the bit if worn to maintain precision.
