Долото по п.1, в котором паз имеет две параллельные боковые стенки.3. Долото по п.2, в котором одна из боковых стенок образует острый угол, а другая образует тупой угол.4. Долото по п.2, в котором клин прикреплен непосредственно рядом со стенкой, наклоненной под тупым углом.5. Долото по п.1, в котором клин имеет две стороны, наклоненные под тупым углом.6. Долото по п.1, дополнительно включающее один или более болтов, проходящих через каждый клин и прикрепляющих клин вместе с лапой к корпусу долота.7. Долото по п.1, в котором паз имеет две боковые стенки, непараллельные одна другой.8. Долото по п.7, в котором первая из боковых стенок проходит примерно прямо наружу от центральной оси корпуса долота.9. Долото по п.8, в котором клин прикреплен непосредственно у первой боковой стенки.10. Долото по п.1, в котором наклоненная под тупым углом боковая стенка клина прикреплена непосредственно у стороны лапы, наклоненной под острым углом.11. Долото по п.1, в котором от каждой лапы в корпус долота отходит шпонка.12. Долото для бурения подземных пород, включающее:одну или более лап с соответствующими шарошками;корпус долота, имеющий лопасть и паз для установки в него лапы, при этом паз имеет две параллельные боковые стенки так, что одна из боковых стенок образует острый угол, а другая образует тупой угол; иодин или более клиньев между лапой и пазом, фиксирующих лапу внутри паза.13.
