Bosch DSBE1012 12 in Straight Drill Bit Extension 1/4 Hex

Product Description

The ROBERT BOSCH TOOL GROUP DSBE1012 is a 12-inch straight extension for drill bits, designed to reach deep into materials where standard bit length falls short. It features a 1/4-inch hex shank for fast, tool-free installation into any hex-compatible chuck or quick-connect driver. The full-cone threaded tip locks onto compatible bits securely, and the Hex Power Groove design reduces slippage under load. This extension is sold in a package of 20 units, making it a practical restocking choice for contractors, electricians, and plumbers who drill through framing, block, or panel assemblies on a daily basis.

The DSBE1012 is suited for use in residential and light commercial construction and renovation. Electricians running wire through studs, plumbers drilling for pipe runs, and HVAC techs routing flex or low-voltage wiring through tight framing bays will find the 12-inch reach especially useful. It pairs with standard spade bits, auger bits, and other accessories that accept a full-cone threaded tip connection.

Installation Notes

Installation requires no tools — insert the hex shank into a compatible chuck or quick-connect driver until it clicks or seats fully. Ensure the bit is threaded firmly onto the full-cone tip before drilling to prevent separation under load. Always verify the connected bit is rated for the material being drilled. Follow applicable workplace safety standards when operating rotary power tools.
