Drill bit set YATO YT-33015 — hinge drill bits, 90 mm length, 5 pieces

YATO YT-33015 is a set of five hinge drill bits with a 90 mm working length, designed for drilling deep or recessed hinge holes and other joinery applications. These hinge-type bits are intended for use with portable drills and drill drivers where a longer reach and stable hole geometry are required. The 5-piece set ensures uniform hole sizes across multiple fittings and provides spare bits for frequent tasks.

Advantages

The hinge drill bits offer consistent hole depth and straightness due to their extended shank design and precision-ground tips. Manufactured for compatibility with common drill chucks, the set reduces downtime by including multiple identical pieces for repetitive installation work. The 90 mm length allows access into recessed hinge cups and other deep mounting locations while maintaining control and stability during drilling.

Suitable for

• Drilling hinge cups and fittings in cabinet and furniture assembly
• Creating recessed holes in doors, frames and panels
• Joinery tasks requiring a 90 mm bit length and consistent hole diameter
• Replacement bits for on-site carpentry and maintenance work

Key specifications

• Quantity in set: 5 pieces
• Working length: 90 mm
• Type: hinge / deep-reach drill bits
• Compatible tool: electric drill or drill driver with matching chuck capacity

How to use

Select a drill with a chuck that securely holds the hinge bit shank and set the drill to a moderate speed suitable for the material being drilled. Mark and center the drilling location, clamp the workpiece if possible, and align the bit at a 90° angle to the surface. Apply steady pressure while drilling to reach the required depth, withdraw periodically to clear chips if drilling into softwood or laminated materials, and stop at the required depth to avoid over-penetration. Replace bits from the set as they wear to maintain consistent hole quality.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. For clean holes in laminated or veneered surfaces, consider backing the workpiece or using a sacrificial pad to reduce splintering. Match drill speed and feed pressure to the material—lower speeds for metal or hard composites and moderate speeds for wood and MDF.
