Drill Bit Set GEKO G64999 with depth stops, 3–16 mm range

GEKO G64999 drill bit set with depth stops provides a selection of twist drills covering diameters from 3 mm to 16 mm, designed for controlled-depth drilling in materials compatible with standard HSS or carbide twist bits. The set is intended for tasks where consistent hole depth is required, such as dowel, hinge and repetitive installation work. Depth stops allow accurate, repeatable drilling without over-penetration.

Advantages

The set combines a wide diameter range with adjustable depth stops to deliver precise, repeatable hole depths. Each drill bit is suitable for standard drill chucks and supports straightforward setup and measurement. Using depth stops reduces the need for constant manual measurement and helps prevent damage to underlying layers or components. The assortment minimizes tool changes on jobs that require multiple hole sizes.

Suitable for

• Dowel and biscuit drilling in furniture and joinery
• Hinge and mounting plate installations
• Repetitive through- or blind-hole drilling where consistent depth is required
• Workshop and site tasks with portable or bench-mounted drills

Key specifications

• Diameter range: 3 mm to 16 mm
• Includes multiple individual drill sizes within the range for common hole diameters
• Equipped with adjustable depth stops for controlled drilling depth
• Compatible with standard drill chucks and handheld or stationary drills
• Intended for materials suitable for twist drill use (wood, plastics, soft metals depending on drill material)

How to use

Select the drill bit size appropriate for the hole diameter required, fit the bit securely in the drill chuck and position the depth stop on the bit shaft to the desired drilling depth. Tighten the depth stop and mount the drill. Begin drilling at low speed to seat the bit, then use the appropriate speed for the material while maintaining steady pressure. For blind holes, stop when the depth stop contacts the drill chuck or collar to ensure the set depth; for through-holes, verify alignment and feed evenly to avoid bit wandering.

Usage recommendations

Use cutting fluid or appropriate lubrication when drilling metals; select drill speeds and feed rates according to the material. Inspect depth stops and bit condition before use and replace worn bits to maintain hole accuracy. When drilling into laminated or veneered surfaces, use backing support to reduce splintering.
