Makes it possible to create flat holes and consistent depths with standard drill bits, reducing rework and improving finish quality. Saves time on projects by letting you use familiar bits in tight or deep spaces instead of buying special long bits. Key benefits Reach and precision: extends drilling depth while maintaining control for flat-bottom or through-holes. Versatile compatibility: accepts standard shank drill bits, so you can use the bits you already own for a wide range of woodworking tasks. Durable performance: solid metal construction provides stable operation and long service life for both professional and DIY use.
