Frequently Asked Questions

Verify the paper drill manufacturer, model, required bit style, and hole diameter. Style E bits are used with certain European-style machines, including equipment associated with Uchida, MBM, Standard Citoborma, and Corta, but the machine documentation should remain the final authority. The letter style identifies the shank and chuck relationship, so matching only the visible hole size is not enough. Record the full specification beside the machine or in the supply cabinet. When replacement paper drill bits are ordered, this record helps prevent a similar-looking bit with the wrong shank from being selected. If an older machine has no readable label, use the existing bit markings and the equipment manual rather than estimating from shape.

Base the diameter on the finished document and the item that must pass through the hole. The hole should provide enough clearance for the intended post, ring, fastener, or filing mechanism without removing more paper than necessary. For repeat work, inspect a correctly finished sample and record the bit size used. When a new job is being planned, measure the hardware and test the fit in scrap stock before drilling the full run. A hole that is too small can slow assembly or tear when the document is opened. A hole that is too large can allow movement and weaken the edge. Cover thickness and laminated sheets also affect fit, so the trial stack should include the same materials as the finished job.

Yes. The machine determines the chuck system, drilling depth, spindle arrangement, stack support, and operating method. Even when a Style E bit fits the chuck, the machine rating still controls how much material can be drilled safely and how the stack should be positioned. Single-spindle equipment may suit custom spacing, while multiple-spindle equipment can reduce setup time for repeated patterns. The selection of paper drills includes different capacities and configurations, which is why the bit specification should never be separated from the machine specification. Confirm the back gauge, side guide, spindle spacing, and stack limit before a production run. Accurate setup matters as much as a sharp bit when several holes must align across many documents.

Rough holes can result from a dull bit, excessive stack height, poor paper support, packed chips, incorrect feed pressure, or a worn drill block. Inspect these conditions one at a time instead of assuming the bit is defective. The cutting edge should enter the stack cleanly, and paper chips should move through the hollow centre without building up. Coated or laminated materials may require a smaller test stack because they create different friction than plain paper. The stack must sit flat against the guides so sheets do not shift during drilling. If the exit side is ragged, inspect the drill block and bit condition. If the hole is scorched or the machine feels strained, stop the run and address heat, chip clearance, or sharpness before continuing.

Keep a suitable drill block, chip-clearing tool, approved lubricant, sharpening method, and at least one spare bit in the sizes used most often. The spare should carry the same Style E specification as the installed bit so it can be fitted without guesswork. Drill blocks wear gradually and should be inspected before the groove becomes deep enough to reduce support under the stack. Chip-clearing tools help remove compacted paper safely from hollow bits. The paper drill accessories range also includes tools for maintenance and bit handling, but each item still needs to match the equipment. Store bits in protective tubes or holders so their cutting edges are not damaged between jobs.
